Referring to fig. 13 to 15, fig. 13 is a schematic view of a first hinge assembly 30a, fig. 14 is a schematic view of a second hinge assembly 30b, and fig. 15 is a schematic view of a third hinge assembly 30 c.

Next, the hinge assembly 30 of the present embodiment will be described by taking the first hinge assembly 30a located between the upper end of the first door body 201 and the box body 10 as an example, and the description of the other hinge assemblies can refer to the description of the first hinge assembly 30 a.

Referring to fig. 16 to 26, the hinge assembly 30 (or the first hinge assembly 30a) further includes a positioning shaft 311 and a positioning groove 321, the positioning shaft 311 is disposed on one of the first hinge member 32 and the second hinge member 31, and the positioning groove 321 is disposed on the other of the first hinge member 32 and the second hinge member 31.

Here, the positioning groove 321 is provided in the first hinge member 32, and the positioning shaft 311 is provided in the second hinge member 31.

Specifically, the first hinge member 32 is located on the door 20, and the second hinge member 31 is located on the box 10.

The first hinge member 32 includes a first hinge member body 323, a positioning slot 321 recessed in the first hinge member body 323, and a driving slot 322, and the first hinge member body 323 is fixed to the door body 20 by a screw 324.

The second hinge 31 includes a second hinge body 313, a positioning shaft 311 protruding out of the second hinge body 313, and a driving shaft 312, and the second hinge body 313 and the box 10 are fixed to each other.

In this embodiment, the positioning slot 321 includes an initial position a1 and a first stop position a2, the driving slot 322 includes a first end 3221 and a second end 3222 that are oppositely disposed, when the door body 20 is in the closed state, the positioning shaft 311 is located at the initial position a1, the driving shaft 312 is located at the first end 3221, and when the door body 20 is in the opening process, the driving shaft 312 moves in the driving slot 322 to drive the positioning shaft 311 to move from the initial position a1 to the first stop position a 2.

The box 10 comprises an outer side surface 12 adjacent to the hinge assembly 30 and on an extension section of a rotation path of the door body 20, the door body 20 comprises a front wall 22 far away from the accommodating chamber S and a side wall 23 always clamped between the front wall 22 and the accommodating chamber S, and a side edge 24 is arranged 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 pivoting side P1) or a right side surface (corresponding to the right pivoting side P2) of the casing 10, the different pivoting 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 walls 23 are side surfaces of the door body 20.

The driving slot 322 includes a first section L1 and a second section L2 connected between a first end 3221 and a second end 3222.

With reference to fig. 17 and 18, 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, that is, the protrusion 21 is limited in the groove 11, the positioning shaft 311 is located at the initial position a1, the driving shaft 312 is located at the first end 3221, and the driving shaft 312 limits the movable plate 60 from disengaging from the driving groove 322.

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, the outer side surface 12 and the side wall 23 are located on the same plane, which can ensure smoothness in appearance, improve aesthetic appearance, and facilitate installation of the door body 20, but not limited thereto.

Referring to fig. 19 and 20, when the door 20 is in the process of opening from the closed state to the first opening angle α 1, the positioning shaft 311 is kept at the initial position a1, the driving shaft 312 moves in the first section L1 around the positioning shaft 311 to drive the first engaging portion 21 to disengage from the second engaging portion 11, and the driving shaft 312 restricts the movable plate 60 from disengaging from the driving groove 322.

Specifically, the protrusion 21 gradually disengages from the groove 11 through the notch 111, and at the same time, the vertical beam 40 rotates toward a side close to the accommodating chamber S to enable the first door body 201 and the vertical beam 40 to have the 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.

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.

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. 21 and 22, when the door 20 is opened from the first opening angle α 1 to the second opening angle α 2, the driving shaft 312 moves in the second segment L2 to drive the positioning shaft 311 to move from the initial position a1 to the first stop position a2, and meanwhile, the driving shaft 312 moves from the first position 3221 to the second position 3222, and the driving shaft 312 restricts the movable plate 60 from disengaging from the driving groove 322.

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 ensure the opening degree of the box 10 as much as possible and avoid the problem that the drawers, racks, and the like in the box 10 cannot be opened due to interference of the door body 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.

In another embodiment, the positioning slot 321 further includes a second stop position A3 located at the side of the initial position a1 away from the first stop position a2, the driving slot 322 further includes a third segment L3 and a fourth segment L4 located between the second segment L2 and the second end 3222, the movable plate 60 covers the first segment L1, the second segment L2, the third segment L3 and a portion of the fourth segment L4 of the driving slot 322, and the movable plate 60 only exposes a region close to the second end 3222.

Referring to fig. 23 and 24, 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 driving shaft 312 moves in the third segment L3 to drive the positioning shaft 311 to move from the first stop position a2 to the second stop position A3, 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, etc. in the box 10, and the driving shaft 312 restricts the movable plate 60 from separating from the driving groove 322.

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.

With reference to fig. 25 and 26, 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 positioning shaft 311 is kept at the second stop position a3, the driving shaft 312 moves in the fourth segment L4 with the positioning shaft 311 as a center, and when the driving shaft 312 moves to the second end 3222, the driving shaft 312 and the movable plate 60 are separated from each other, and at this time, the movable plate 60 can be taken out of the driving groove 322.

Here, the side edge 24 is always located on the side of the outer side surface 12 close to the receiving 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 positioning slot 321 further includes a pivot position a4 located on a side of the second stop position A3 away from the initial position a1, the driving slot 322 further includes a transition section L located 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 located on a straight line, while the pivot position a4 is not located on the straight line, and the pivot position a4 forms an angle with the straight line.

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 driving shaft 312 moves in the transition section L to drive the positioning shaft 311 to move from the second stop position A3 to the pivot position a4, and then the positioning shaft 311 remains at the pivot position a4, and the driving shaft 312 moves in the fourth section L4 with the positioning 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 positioning shaft 311 is maintained at the second stop position A3, the door 20 may slide or sway because a parallel portion exists between the fourth segment L and the portion between the first stop position a2 and the second stop position A3.

In the present embodiment, when the driving shaft 312 moves in the fourth section L4, the positioning shaft 311 is maintained 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 positioning shaft 311 at the initial position a1, the center of the positioning shaft 311 at the first stop position a2, and the center of the positioning shaft 311 at the second stop position A3.

The distance between the center of the positioning shaft 311 and the side edge 24 when the positioning shaft 311 is located at the initial position a1 is greater than the distance between the center of the positioning shaft 311 and the side edge 24 when the positioning shaft 311 is located at the first stop position a2, and the distance between the center of the positioning shaft 311 and the side edge 24 when the positioning shaft 311 is located at the initial position a1 is less than the distance between the center of the positioning shaft 311 and the side edge 24 when the positioning shaft 311 is located at the second stop position A3.

The distance between the center of the positioning shaft 311 at the initial position a1 and the front wall 22 is greater than the distance between the center of the positioning shaft 311 at the first stop position a2 and the front wall 22, and the distance between the center of the positioning shaft 311 at the initial position a1 and the front wall 22 is less than the distance between the center of the positioning shaft 311 at the second stop position A3 and the front wall 22.

The distance between the center of the positioning shaft 311 and the side wall 23 when the positioning shaft 311 is located at the initial position a1 is greater than the distance between the center of the positioning shaft 311 and the side wall 23 when the positioning shaft 311 is located at the first stop position a2, and the distance between the center of the positioning shaft 311 and the side wall 23 when the positioning shaft 311 is located at the initial position a1 is less than the distance between the center of the positioning shaft 311 and the side wall 23 when the positioning shaft 311 is located at the second stop position A3.

A first distance is formed between the center of the positioning shaft 311 and the side edge 24, a second distance is formed between the center of the positioning shaft 311 and the front wall 22, and a third distance is formed between the center of the positioning shaft 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 20 is continuously opened 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 20 is continuously opened 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 20 is continuously opened 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.

In summary, the present invention can ensure the first matching portion 21 to be smoothly separated from the second matching portion 11 through the matching structure of the positioning shaft 311, the positioning groove 321, the driving shaft 312 and the driving groove 322, when the refrigerator 100 includes the vertical beam 40, it can be ensured that the protrusion 21 on the vertical beam 40 is smoothly separated from the groove 11 on the refrigerator body 10 without mutual interference at the initial opening stage of the door body 20, and then the door body 20 moves from the pivoting side P toward the accommodating chamber S during the continuous opening process of the door body 20 to avoid the door body 20 from interfering with the surrounding cabinets or walls during the opening process, which is suitable for the embedded cabinets or the scenes with small space for accommodating the refrigerator 100, and in addition, when the opening angle of the door body 20 is larger, the door body 20 moves from the accommodating chamber S toward the pivoting side P to avoid the door body 20 from obstructing the opening of the drawers, shelves and the like in the refrigerator body 10, and the baffle 60 of the present invention can avoid dust and dust from being blocked by the baffle 60, Impurities and the like enter the driving groove 322.
