Referring to fig. 4, when the door 20 is in the process of being opened from the closed state to the first opening angle α 1, the hinge assembly 30 drives the door 20 to rotate in place relative to the cabinet 10.
Here, when the door 20 is in the process of being opened from the closed state to the first opening angle α 1, the door 20 rotates in place relative to the box 10, that is, the door 20 only rotates without generating displacement in other directions, so that a phenomenon that the first engaging portion 61 cannot be disengaged from the second engaging portion 62 due to displacement of the door 20 in a certain direction can be effectively avoided, and a phenomenon that the door 20 cannot be normally opened due to displacement of the door 20 in a certain direction can be effectively avoided, and specific reference can be made to the following description of specific examples.
Referring to fig. 5, when the door 20 is in the process of continuously opening from the first opening angle α 1 to the second opening angle α 2, the hinge assembly 30 drives the door 20 to move from the pivot side P toward the accommodating chamber S.
Here, when the door 20 is in the process of continuously opening from the first opening angle α 1 to the second opening angle α 2, the door 20 moves toward one side of the accommodating chamber S, that is, at this time, the door 20 both rotates relative to the box 10 and displaces relative to the box 10 along the first direction X, so that the distance that the door 20 protrudes out of the box 10 toward the side away from the accommodating chamber S during the rotation process is greatly reduced, that is, the displacement of the door 20 along the first direction X offsets the portion of the door 20 protruding out of the box 10 along the second direction Y during the rotation process, thereby preventing the door 20 from interfering with peripheral cabinets or walls during the opening process, and being suitable for embedded cabinets or scenes with small space for accommodating the refrigerator 100.
Referring to fig. 6, when the door 20 is in the process of continuously opening from the second opening angle α 2 to the third opening angle α 3, the hinge assembly 30 drives the door 20 to move from the accommodating chamber S toward the pivoting side P.
Here, when the door 20 is in the process of continuously opening from the second opening angle α 2 to the third opening angle α 3, the door 20 moves toward one side of the pivot side P, that is, at this time, the door 20 rotates relative to the box 10 and displaces along the second direction Y relative to the box 10, so that the door 20 can be kept away from the box 10 as far as possible, the opening degree of the box 10 is ensured, and the problem that drawers, racks and the like in the box 10 cannot be opened due to interference of the door 20 is avoided.
Referring to fig. 7, when the door 20 is in the process of continuously opening from the third opening angle α 3 to the maximum opening angle α 4, the hinge assembly 30 drives the door 20 to rotate in place relative to the box 10.
With continued reference to fig. 1 to 7, in a specific example of the present invention, the door 20 is provided with a first engaging portion 21, and the box 10 is provided with a second engaging portion 11.
Referring to fig. 3, when the door 20 is in the closed state, the first engaging portion 21 and the second engaging portion 11 are engaged with each other.
Here, the first engaging portion 21 and the second engaging portion 11 are engaged with each other to close the door 20 and the box 10, and the specific form of the first engaging portion 21 and the second engaging portion 11 may be determined according to actual situations.
Referring to fig. 4, when the door 20 is in the process of being opened from the closed state to the first opening angle α 1, the hinge assembly 30 drives the door 20 to rotate in place relative to the box 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 being opened from the closed state to the first opening angle α 1, the door 20 rotates in place relative to the box 10, that is, the door 20 only rotates without generating displacement in other directions, so that the phenomenon that the first engaging portion 21 cannot be separated from the second engaging portion 11 due to the displacement in a certain direction of the door 20 can be effectively avoided.
It should be noted that the refrigerator 100 in this example may be a single-door refrigerator having the first and second fitting portions 21 and 11, or a side-by-side refrigerator, a multi-door refrigerator, or the like having the first and second fitting portions 21 and 11.

Here, if the first door 201 'generates a displacement in the horizontal direction when being opened, the first door 201' and the second door 202 'may generate mutual interference to cause that the first door 201' and the second door 202 'cannot be normally opened, and the first door 201' and the second door 202 'rotate in situ when the refrigerator 100' of this example is opened, so that the mutual interference between the adjacent first door 201 'and the second door 202' can be effectively avoided.
Of course, the type of the refrigerator 100 is not limited to the above specific examples, and may be determined according to actual circumstances.
In the present embodiment, referring to fig. 10 and 11, the first engaging portion 61 is a hook 61, the hook 61 is an elastic member, the second engaging portion 62 is a protrusion 62, and the protrusion 62 deforms when the door 20 is in the closed state.
That is to say, when the door 20 is in the closed state, the protruding portion 62 and the hook 61 are in interference fit, so that the closing effect of the door 20 is enhanced.
The first hinge part 32 includes a first hinge body 323 and first driving parts 321, 322 connected to the first hinge body 323, the second hinge part 31 includes a second hinge body 313 and second driving parts 311, 312 connected to the second hinge body 313, the first driving parts 321, 322 are pivotally connected to the second driving parts 311, 312, the hook 61 protrudes out of the first hinge body 323 in the horizontal direction, and the protrusion 62 protrudes out of the second hinge body 313 in the horizontal direction.
The hook 61 is disposed on a side of the first hinge body 323 away from the pivoting side P, the protrusion 62 is disposed on a side of the second hinge body 313 away from the pivoting side P, and the protrusion 62 may be a protruding structure of an end of the second hinge body 313, that is, the protrusion 62 and the second hinge body 313 are integrally formed.

With reference to fig. 17 to 27, the hinge assembly 30 (or the first hinge assembly 30a) includes a first shaft 311, a first slot 321, and a second shaft 312 and a second slot 322, which are engaged with each other, the first shaft 311 serves as one of the first driving member and the second driving member, the first slot 321 serves as the other of the first driving member and the second driving member, the second shaft 312 serves as one of the first driving member and the second driving member, and the second slot 322 serves as the other of the first driving member and the second driving member.
That is, the distribution form of the hinge assembly 30 may include various cases, in the first example, the first shaft body 311 and the second shaft body 312 are located in the box body 10, and the first slot body 321 and the second slot body 322 are located in the door body 20; in the second example, the first shaft 311 and the second shaft 312 are located on the door 20, and the first slot 321 and the second slot 322 are located on the box 10; in the third example, the first shaft 311 and the second chute 322 are located in the box 10, and the first chute 321 and the second shaft 312 are located in the door 20; in the fourth example, the first shaft 311 and the second slot 322 are located in the door 20, and the first slot 321 and the second shaft 312 are located in the box 10.
Here, in the first example, the first shaft 311 and the second shaft 312 are located in the box 10, and the first slot 321 and the second slot 322 are located in the door 20.
Specifically, the hinge assembly 30 includes a first hinge member 32 and a second hinge member 31 that are engaged with each other, the first hinge member 32 is located at the door 20, and the second hinge member 31 is located at the box 10.
The first hinge 32 includes a first hinge body 323, and a first slot 321 and a second slot 322 recessed in the first hinge body 323, and the first hinge body 323 is fixed to the door 20 by a screw 324.
The second hinge 31 includes a second hinge body 313, and a first shaft 311 and a second shaft 312 protruding out of the second hinge body 313, and the second hinge body 313 and the box 10 are fixed to each other.
The first slot 321 includes a first stop position a2, a second stop position A3 and an initial position a1 between the first stop position a2 and the second stop position A3 at both ends of the first slot 321, and the second slot 322 includes a first section L1, a second section L2, a third section L3 and a fourth section L4 which are connected in sequence.
In the present embodiment, the box 10 includes an outer side surface 12 adjacent to the hinge assembly 30 and on an extension of a rotation path of the door body 20, the door body 20 includes a front wall 22 far from the accommodating chamber S and a side wall 23 always interposed between the front wall 22 and the accommodating chamber S, and a side edge 24 is provided between the front wall 22 and the side wall 23.
Here, the outer side surface 12 is a left side surface (corresponding to the left pivot side P1) or a right side surface (corresponding to the right pivot side P2) of the casing 10, the different pivot sides P correspond to the different outer side surfaces 12, the front wall 22 is a front surface of the door body 20, and the side wall 23 is a side surface of the door body 20.
Referring to fig. 18 and 19, when the door 20 is in the closed state, the first shaft 311 is located at the initial position a1, the second shaft 312 is located at a side of the first section L1 away from the second section L2, the protrusion 21 is limited in the groove 11, and the hook 61 and the protrusion 62 are engaged with each other.
Specifically, the protrusion 21 is limited in the groove 11 so that the vertical beam 40 extends to the second door body 202, that is, the vertical beam 40 is attached to the inner side surfaces of the first door body 201 and the second door body 202 at this time, so as to prevent the cold air in the accommodating chamber S from leaking to the outside of the refrigerator 100.
In addition, when the door body 20 is in the closed state, the outer side surface 12 and the side wall 23 are located on the same plane, and at this time, smoothness in appearance can be ensured, the appearance is improved, and the installation of the door body 20 is also facilitated, but not limited thereto.
Referring to fig. 20 and 21, when the door 20 is in the process of opening from the closed state to the first opening angle α 1, the first shaft 311 is kept at the initial position a1, and the second shaft 312 moves in the first section L1 around the first shaft 311, at this time, the door 20 rotates in place relative to the box 10 to separate the protrusion 21 from the groove 11, and the hook 61 is separated from the protrusion 62.
Specifically, the protrusion 21 gradually separates from the groove 11 through the notch 111, the hook 61 deforms to separate from the protrusion 62, and meanwhile, the vertical beam 40 rotates toward a side close to the accommodating chamber S, so that the first door body 201 and the vertical beam 40 have a first folding angle β therebetween.
Here, when the protrusion 21 is completely disengaged from the groove 11, the first folding angle β is preferably maintained at less than 90 degrees to prevent the vertical beam 40 from affecting the opening and closing of the second door body 202.
It should be noted that, because the projection 21 and the groove 11 are in arc-shaped fit, when the door 20 is in the closed state, the projection 21 and the groove 11 are mutually limited in the first direction X or the second direction Y, if the door 20 is displaced along the first direction X or the second direction Y during the process of opening the door 20 to the first opening angle α 1, the projection 21 and the groove 11 will be mutually interfered and jammed, so that the projection 21 cannot be separated from the groove 11, and the door 20 cannot be opened.
In the present embodiment, the door 20 rotates in situ relative to the box 10 during the process of opening the door 20 to the first opening angle α 1, so as to ensure that the door 20 does not displace along the first direction X or the second direction Y during the process, and further ensure that the protrusion 21 can smoothly separate from the groove 11, and ensure that the hook 61 smoothly separates from the protrusion 62.
Here, the first opening angle is not greater than 10 °, that is, the projection 21 may not be restricted by the groove 11 during the process of opening the door 20 to about 10 °, and at this time, the projection 21 may be completely separated from the groove 11, or the projection 21 may not interfere with the groove 11 even if it is displaced in the first direction X or the second direction Y.
Meanwhile, the hook 61 can be completely separated from the protrusion 62 during the process of opening the door 20 to about 10 °, and generally, during the process of opening the door 20, the hook 61 is separated from the protrusion 62 first, and then the protrusion 21 is separated from the groove 11.
In addition, if the outer side surface 12 and the side wall 23 are located on the same plane when the door 20 is in the closed state, the side edge 24 will protrude out of the outer side surface 12 along the second direction Y during the rotation process (the protruding distance is generally not more than 3 mm).
Referring to fig. 22 and 23, when the door 20 is in the process of continuously opening from the first opening angle α 1 to the second opening angle α 2, the second shaft 312 moves in the second segment 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 the door 20 interfering with the surrounding cabinets or walls during the opening process.
Specifically, the vertical beam 40 and the first door 201 are kept relatively stationary, 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 protrusion 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 to drive the vertical beam 40 to gradually rotate to the fully unfolded state, that is, at this time, the vertical beam 40 is attached to the inner side surfaces of the first door 201 and the second door 202 at the same time.
In addition, the side edge 24 moves to a side of the outer side surface 12 close to the accommodating chamber S, that is, the hinge assembly 30 drives the side edge 24 to move toward the side close to the accommodating chamber S, so that interference with surrounding cabinets or walls and the like due to the fact that the side edge 24 protrudes out of the outer side surface 12 can be avoided during the opening process of the door body 20.
Here, in order to secure the opening degree of the box 10 as much as possible and avoid the problem that the drawer, the rack, and the like in the box 10 cannot be opened due to interference of the door 20, the side edge 24 moves toward the side close to the accommodating chamber S into the plane of the outer side surface 12, and then the hinge assembly 30 drives the side edge 24 to move in the plane and gradually approach the accommodating chamber S.
That is, at this time, on the basis of ensuring that the side edge 24 does not protrude out of the corresponding outer side surface 12, the side edge 24 is as close as possible to the outer side surface 12, so that interference between the door 20 and a peripheral cabinet or wall in the opening process can be avoided, and the opening degree of the box 10 can be ensured as much as possible.
Referring to fig. 24 and 25, when the door 20 is in the process of continuously opening from the second opening angle α 2 to the third opening angle α 3, the second shaft 312 moves in the third segment 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 prevent the door 20 from obstructing the opening of the drawers, racks, and the like in the box 10.
Specifically, the vertical beam 40 and the first door body 201 are kept relatively stationary.
In addition, the lateral edges 24 move in the plane of the outer lateral surface 12 and gradually approach the housing chamber S.
It can be understood that, when the door 20 is in the process of continuing to open from the second opening angle α 2 to the third opening angle α 3, if the door 20 rotates in place relative to the box 10, the side edge 24 gradually moves toward a side close to the accommodating chamber S, and meanwhile, the door 20 gradually moves close to the accommodating chamber S, and the door 20 may obstruct the opening of the drawer, the rack, and the like in the box 10, that is, the opening of the box 10 may be reduced.
The hinge assembly 30 of the present embodiment drives the side edge 24 to move in the plane of the outer side surface 12, so that the door 20 is away from the box 10 as much as possible, the opening degree of the box 10 is ensured, the problem that drawers, racks and the like in the box 10 cannot be opened due to interference of the door 20 is avoided, and the side edge 24 is prevented from protruding out of the outer side surface 12 in the direction away from the accommodating chamber S.
Referring to fig. 26 and 27, when the door 20 is in the process of continuously opening from the third opening angle α 3 to the maximum opening angle α 4, the first shaft 311 is kept at the second stop position a3, and the second shaft 312 moves in the fourth segment L4 around the first shaft 311.
In particular, the lateral edge 24 is always located on the side of the outer lateral surface 12 close to the housing chamber S.
In addition, 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 20 to 90 °, the door 20 first generates displacement along the first direction X, so as to prevent the door 20 from interfering with peripheral cabinets or walls during the opening process, and then the door 20 generates displacement along the second direction Y, so as to prevent the door 20 from obstructing the opening of drawers, racks, and the like in the box 10, and finally, after 90 °, the door 20 rotates in place relative to the box 10 to further open the door 20.
It can be understood that, when the door 20 is opened from the closed state to the first opening angle α 1, because the door 20 rotates in situ relative to the box 10, the door 20 slightly protrudes out of the box 10 toward the side (left side) away from the accommodating chamber S, and when the door 20 is continuously opened from the first opening angle α 1 to the second opening angle α 2, the displacement of the door 20 along the first direction X may offset all portions of the door 20 protruding out of the box 10 along the second direction Y during the whole rotation process, and then when the door 20 is continuously opened from the second opening angle α 2 to the third opening angle α 3, the displacement of the door 20 along the second direction Y may enable the door 20 not to protrude out of the box 10 and ensure the opening degree of the box 10 as much as possible.
In other embodiments, the first slot 321 further includes a pivot position a4 on a side of the second stop position A3 away from the initial position a1, the second slot 322 further includes a transition section L between the third section L3 and the fourth section L4, and a line connecting the second stop position A3 and the pivot position a4 is parallel to the transition section L.
The first stop position A2, the initial position A1, and the second stop position A3 are on a straight line, and the pivot position A4 is not on the straight line, and the pivot position A4 is at an angle to the straight line.
When the door 20 is in the process of continuously opening from the third opening angle α 3 to the maximum opening angle α 4, the second shaft 312 moves in the transition section L to drive the first shaft 311 to move from the second stop position A3 to the pivot position a4, and then the first shaft 311 is kept at the pivot position a4, and the second shaft 312 moves in the fourth section L4 with the first shaft 311 as a center.
Here, when the door 20 rotates in place relative to the housing 10 and continues to open the door 20, if the first shaft 311 is maintained at the second stop position A3, the door 20 may slide or sway because a parallel portion exists between the portion between the first stop position a2 and the second stop position A3 and the fourth segment L.
In the embodiment, when the second shaft 312 moves in the fourth section L4, the first shaft 311 is kept at the pivot position a4 without shaking, so that the problem of side sliding or shaking of the door 20 is solved.
In the present embodiment, a first connection line passing through the side edge 24 of the door body 20 is defined by the center of the first shaft body 311 at the initial position a1, the center of the first shaft body 311 at the first stop position a2, and the center of the first shaft body 311 at the second stop position A3.
The distance between the center and the side edge 24 of the first shaft body 311 at the initial position a1 is greater than the distance between the center and the side edge 24 of the first shaft body 311 at the first stop position a2, and the distance between the center and the side edge 24 of the first shaft body 311 at the initial position a1 is less than the distance between the center and the side edge 24 of the first shaft body 311 at the second stop position A3.
The distance between the center of the first shaft body 311 at the initial position a1 and the front wall 22 is greater than the distance between the center of the first shaft body 311 at the first stop position a2 and the front wall 22, and the distance between the center of the first shaft body 311 at the initial position a1 and the front wall 22 is less than the distance between the center of the first shaft body 311 at the second stop position A3 and the front wall 22.
The distance between the center of the first shaft body 311 at the initial position a1 and the side wall 23 is greater than the distance between the center of the first shaft body 311 at the first stop position a2 and the side wall 23, and the distance between the center of the first shaft body 311 at the initial position a1 and the side wall 23 is less than the distance between the center of the first shaft body 311 at the second stop position A3 and the side wall 23.
A first distance is formed between the center of the first shaft body 311 and the side edge 24, a second distance is formed between the center of the first shaft body 311 and the front wall 22, and a third distance is formed between the center of the first shaft body 311 and the side wall 23, and the first distance, the second distance and the third distance are changed when the door body 20 is opened.
When the door body 20 is in the process of continuously opening from the first opening angle α 1 to the second opening angle α 2, the first distance, the second distance and the third distance all decrease, when the door body 20 is in the process of continuously opening from the second opening angle α 2 to the third opening angle α 3, the first distance, the second distance and the third distance all increase, and when the door body 20 is in the process of continuously opening from the third opening angle α 3 to the maximum opening angle α 4, the first distance, the second distance and the third distance all remain unchanged.
