Detailed Description

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes in accordance with the embodiments are within the scope of the present invention.

In the various drawings of the present invention, some dimensions of structures or portions are exaggerated relative to other structures or portions for convenience of illustration, and thus, are used only to illustrate the basic structure of the subject matter of the present invention.

Also, terms such as "upper," "above," "lower," "below," "left," "right," and the like used herein to denote relative spatial positions are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Referring to fig. 1 to 4, 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 cabinet 10 includes a receiving chamber S and a pivoting side P to which the hinge assembly 30 is connected.

Here, the "pivoting side P" is defined as a region where the door body 20 is rotated with respect to the 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 box 10 includes a left pivoting side P1 and a right pivoting side P2, when the pivoting side P is the left pivoting side P1, the first direction X is a direction from left to right, the second direction Y is a direction from right to left, when the pivoting side P is the right pivoting side P2, the first direction X is a direction from right to left, the second direction Y is a direction from left to right, that is, corresponding to different pivoting sides P, actual directions of the first direction X and the second direction Y are different, and the following description will take 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 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 it is effectively avoided that the door 20 cannot be normally opened due to displacement in a certain direction of the door 20, and reference may be specifically made to the following description of specific examples.

Referring to fig. 4, 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 refrigerator body 10 and displaces relative to the refrigerator body 10 along the first direction X, so that the distance that the door 20 protrudes out of the refrigerator body 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 counteracts the part of the door 20 protruding out of the refrigerator body 10 along the second direction Y during the rotation process, so as to prevent the door 20 from interfering with peripheral cabinets or walls during the opening process, and the refrigerator is suitable for a scenario where the space for accommodating the embedded cabinet or the refrigerator 100 is small.

With continued reference to fig. 1 to 4, 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. 2, 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. 3, 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.

In other specific examples, the refrigerator 100 may not include the first matching portion 21 and the second matching portion 11, and with reference to fig. 5 and 6, the refrigerator 100 is a side-by-side combination refrigerator 100', the refrigerator 100' includes two compartments spaced apart from each other by a fixing beam 200', the refrigerator 100' further includes a first door 201' and a second door 202' corresponding to the two compartments, respectively, the first door 201' and the second door 202' are disposed adjacent to each other, when the refrigerator 100' is in a closed state, both the first door 201' and the second door 202' contact the fixing beam 200' to achieve sealing, and when the first door 201' and/or the second door 202' are opened from the closed state to the first opening angle α 1, the first door 201' and/or the second door 202' rotate in situ relative to the refrigerator body 10 '.

Here, if the first door 201 'generates a displacement in a horizontal direction when being opened, the first door 201' and the second door 202 'may interfere with each other 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 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.

Referring to fig. 7 and 8, in the present embodiment, the door 20 includes a first door 201 and a second door 202 pivotally connected to the casing 10 and arranged in parallel in the horizontal direction.

The refrigerator 100 further includes a vertical beam 40 movably connected to one side of the first door 201 close to the second door 202, and the first engaging portion 21 is disposed at the vertical beam 40.

Here, the vertical beam 40 is movably connected to the right side of the first door 201, the vertical beam 40 and the first door 201 can be connected through the return spring 41, and the vertical beam 40 rotates relative to the first door 201 around the vertical axis, in other words, the vertical beam 40 can rotate relative to the first door 201 and be kept at a predetermined position through the action of the return spring 41.

The first fitting portion 21 is a projection 21 projecting upward from the vertical beam 40.

The second matching portion 11 is fixed on the box 10, for example, the second matching portion 11 is a groove 11 on the base 101, the base 101 is fixed on the top of the accommodating chamber S, one end of the groove 11 has a notch 111, the opening direction of the notch 111 faces forward, the protrusion 21 and the groove 11 are both arc-shaped, and the protrusion 21 enters or separates from the groove 11 through the notch 111 to realize mutual spacing and mutual separation of the protrusion 21 and the groove 11.

Of course, it can be understood that the specific structure of the first and

second matching portions

21 and 11 is not limited to the above description, that is, the first matching portion 21 is not limited to the protrusion 21 at the vertical beam 40, the second matching portion 11 is not limited to the groove 11 matching with the protrusion 21, and the first and

Referring to fig. 12 to 18, the hinge assembly 30 (or referred to as a first hinge assembly 30 a) includes a first shaft 311, a first slot 321, a second shaft 312 and a second slot 322, wherein the first shaft 311 and the second slot are engaged with each other, the first shaft 311 is located in one of the box 10 and the door 20, the first slot 321 is located in the other of the box 10 and the door 20, the second shaft 312 is located in one of the box 10 and the door 20, and the second slot 322 is located in the other of the box 10 and the door 20.

That is, the distribution of the hinge assembly 30 may include various situations, in the first example, the first shaft 311 and the second shaft 312 are located in the box body 10, and the first slot 321 and the second slot 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 and

second shaft bodies

311, 322 are located at the door 20, and the first and

second chute bodies

321, 312 are located at the cabinet 10.

Here, in the first example, the first shaft 311 and the second shaft 312 are located in the box 10, and the first chute 321 and the second chute 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 an initial position A1 and a stop position A2, and the second slot 322 includes a first segment L1 and a second segment L2 connected to each other.

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 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 wall 23 is a side surface of the door body 20.

Referring to fig. 13 and 14, 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, and the protrusion 21 is limited in the groove 11.

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, 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. 15 and 16, 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 within the first section L1 around the first shaft 311, that is, the door 20 rotates in place relative to the box 10 to disengage the protrusion 21 from the groove 11.

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 in the process of opening the door 20 to the first opening angle α 1, so that the door 20 does not displace along the first direction X or the second direction Y in the process, and the protrusion 21 can be smoothly separated 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 in the process of opening the door body 20 to about 10 °, and in this case, 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. 17 and 18, 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 stop position A2, and at this time, the door 20 moves from the pivot side P toward the accommodating chamber S to avoid the door 20 interfering with the surrounding cabinets or walls during the opening process.

Specifically, at this time, the vertical beam 40 and the first door body 201 are kept relatively stationary, that is, the vertical beam 40 and the first door body 201 are kept at the first folding angle β, and at this time, when the door body 20 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, 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 attached to the inner side surfaces of the first door body 201 and the second door body 202 at the same time.

The second opening angle α 2 is not greater than 90 °, that is, in the process of opening the door 20 to 90 °, the door 20 has been displaced along the first direction X, so as to avoid interference between the door 20 and peripheral cabinets or walls during the opening process.

It can be understood that, when the door 20 is opened from the closed state to the first opening angle α 1, the door 20 slightly protrudes out of the box 10 toward the side (left side) away from the accommodating chamber S due to the original rotation of the door 20 relative to the box 10, 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 can counteract all portions of the door 20 protruding out of the box 10 along the second direction Y during the whole rotation process.

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.

In the present embodiment, a first connection line between the center of the first shaft body 311 when located at the initial position A1 and the center of the first shaft body 311 when located at the stop position A2 passes through the side edge 24 of the door body 20, the distance between the center of the first shaft body 311 when located at the initial position A1 and the side edge 24 is greater than the distance between the center of the first shaft body 311 when located at the stop position A2 and the side edge 24, the distance between the center of the first shaft body 311 when located at the initial position A1 and the front wall 22 is greater than the distance between the center of the first shaft body 311 when located at the stop position A2 and the front wall 22, and the distance between the center of the first shaft body 311 when located at the initial position A1 and the side wall 23 is greater than the distance between the center of the first shaft body 311 when located at the stop position A2 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 continuing to open 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.

In another embodiment of the present invention, referring to fig. 1 to 18, a 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.

When the door 20 is in the closed state, the first shaft 311 is located at the initial position A1, and the second shaft 312 is located at a side of the first section L1 away from the second section L2.

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 within the first segment L1 around the first shaft 311.

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 stop position A2, and the door moves from the pivoting side P toward the accommodating chamber S.
