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 made by those skilled in the art according to these embodiments are included in 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.

Referring to fig. 1, a schematic diagram of a refrigeration apparatus 100 according to an embodiment of the invention is shown.

The refrigeration apparatus 100 includes a cabinet 10, a door 20, and a hinge assembly 30 connecting the cabinet 10 and the door 20.

The refrigeration apparatus 100 may be a refrigerator, a freezer, a wine cabinet, etc., and the refrigeration apparatus 100 is taken as the refrigerator as an example.

In addition, the hinge assembly 30 is not only applicable to the refrigeration apparatus 100, but also applicable to other occasions, such as a cabinet, a wardrobe, etc., and the present invention is exemplified by the hinge assembly 30 applied to the refrigerator 100, but not limited thereto.

Referring to fig. 2 to 4, a hinge assembly 30 according to an embodiment of the present invention is schematically illustrated.

The hinge assembly 30 includes a first hinge 31 connected to the cabinet 10, a second hinge 32 connected to the door 20, and a sliding piece 40 connecting the first hinge 31 and the second hinge 32.

Here, the "first hinge 31 connected to the case 10" means that the first hinge 31 is connected to the case 10, and the first hinge 31 may be a separate member attached to the case 10 or a member directly integrally formed on the case 10.

Similarly, the phrase "the second hinge part 32 connected to the door body 20" means that the second hinge part 32 is connected to the door body 20, and the second hinge part 32 may be an independent part mounted to the door body 20 or a part directly integrally formed on the door body 20.

The hinge assembly 30 further includes at least one shaft body 311, 312 positioned at the first hinge member 31, slots 401, 402 positioned at the sliding piece 40 and cooperating with the shaft bodies 311, 312, and a rotation assembly 50 positioned between the sliding piece 40 and the second hinge member 32.

When the hinge assembly 30 is in the opening process, the second hinge member 32 moves together with the sliding piece 40 relative to the first hinge member 31, and then the rotating assembly 50 drives the second hinge member 32 to move relative to the sliding piece 40.

Here, the phrase "at least one shaft 311, 312 located on the first hinge member 31" means that at least one shaft 311, 312 is disposed on the first hinge member 31, the shaft 311, 312 and the first hinge member 31 may be integrally formed, or may be assembled together, and for the explanation of "located" in other parts of the present invention, reference may be made to this description, and details will not be repeated.

It should be noted that "the hinge assembly 30 is in the opening process" means that the second hinge member 32 is opened in a direction away from the first hinge member 31, that is, the second hinge member 32 is acted in one direction to drive the second hinge member 32 to move in a direction away from the first hinge member 31, and when the hinge assembly 30 is mounted on the refrigerator 100, the opening process of the hinge assembly 30 corresponds to the opening process of the door 20.

In this embodiment, the second hinge member 32 and the sliding piece 40 move together relative to the first hinge member 31, and then the rotating assembly 50 drives the second hinge member 32 to move relative to the sliding piece 40, so that it can be seen that two movements are realized in the whole opening process of the hinge assembly 30, the position change of the rotating shaft can be realized in the two movement processes, the movement track of the door body can be effectively controlled, and further the degree of freedom of the opening and closing process of the door body 20 of the refrigerator 100 is improved, especially in the field of embedded refrigerators, and the mutual interference between the door body 20 and the surrounding cabinets or walls in the opening and closing process can be avoided by switching the rotating shaft.

In the first embodiment, referring to fig. 2 to 5, the hinge assembly 30 further includes a first shaft 311 and a second shaft 312 on the first hinge member 31, a first slot 401 and a second slot 402 on the sliding sheet 40, and a third slot 321 and a fourth slot 322 on the second hinge member 32, wherein the first slot 401 and the first shaft 311 are matched with each other, and the second slot 402 and the second shaft 312 are matched with each other.

When the hinge assembly 30 is in the closed state, the first shaft 311 extends into the first slot 401 and the third slot 321 which overlap with each other, the second shaft 312 extends into the second slot 402 and the fourth slot 322 which overlap with each other, and the sliding piece 40 and the second hinge piece 32 are stationary relative to each other.

Here, "overlap with each other" means that the first tank body 401 and the third tank body 321 keep the same shape, and at the same time, the second tank body 402 and the fourth tank body 322 keep the same shape.

When the hinge assembly 30 is in the opening process, the second hinge element 32 moves together with the sliding piece 40 relative to the first hinge element 31 until the first shaft 311 is limited in the first slot 401 and/or the second shaft 312 is limited in the second slot 402, and then the rotating assembly 50 drives the second hinge element 32 to move relative to the sliding piece 40.

In the present embodiment, the locking and unlocking between the first hinge element 31, the second hinge element 32 and the sliding piece 40 can be controlled by the structure of the hinge assembly 30, specifically, the mutual locking between the second hinge element 32 and the sliding piece 40 is controlled first, and then the second hinge element 32 and the sliding piece 40 are controlled to move relative to the first hinge element 31, and then the unlocking between the second hinge element 32 and the sliding piece 40 and the mutual locking between the first hinge element 31 and the sliding piece 40 are controlled, and then the second hinge element 32 is controlled to move relative to the sliding piece 40.

Specifically, in the present embodiment, when the hinge assembly 30 is in the process of being opened from the closed state to the first opening angle α 1, the second hinge 32 and the sliding piece 40 rotate relative to the first hinge 31 around the first rotation axis P1, and when the hinge assembly 30 is in the process of being opened from the first opening angle α 1 to the second opening angle α 2, the second hinge 32 rotates relative to the sliding piece 40 around the second rotation axis P2.

Here, the first rotation axis P1 may be a virtual axis or a physical axis.

The virtual axis refers to an axis body that is not substantially present in the hinge assembly 30, and the physical axis refers to a component actually included in the hinge assembly 30.

In addition, the first rotation axis P1 may be a non-fixed axis or a fixed axis.

The non-fixed shaft means that the position of the first rotating shaft P1 is always in a changing process, that is, the relative position between the first rotating shaft P1 and the cabinet 10 or the door 20 is changed, and the fixed shaft means that the position of the first rotating shaft P1 is fixed, that is, the relative position between the first rotating shaft P1 and the cabinet 10 or the door 20 is fixed.

Similarly, the second rotation axis P2 may be a virtual axis or a solid axis, and the second rotation axis P2 may be a non-fixed axis or a fixed axis, and the second rotation axis P2 and the first rotation axis P1 are offset from each other, that is, the position of the second rotation axis P2 is not consistent with the position of the first rotation axis P1.

It can be seen that the hinge assembly 30 of the present embodiment can effectively control the sequence of the two rotations, and the change of the position of the rotation axis exists in the two rotation processes, so as to effectively control the movement track of the door 20, and further improve the degree of freedom of the opening and closing processes of the door 20 of the refrigerator 100, especially in the field of embedded refrigerators, and the mutual interference between the door 20 and the surrounding cabinets or walls in the opening and closing processes can be avoided by switching the rotation axis.

To further illustrate the movement trace of the hinge assembly 30, referring to fig. 5, a simple schematic diagram of the hinge assembly 30 assembled to the refrigerator 100 and the refrigerator 100 embedded in the cabinet 200 is illustrated as an example.

The box 10 includes an opening 102 and a front end surface 103 surrounding the opening 102, the box 10 further includes an accommodating chamber D and an outer side surface 13 adjacent to the hinge assembly 30 and on an extension section of a rotation path of the door 20, the door 20 includes a front wall 21 far away from the accommodating chamber D and a side wall 22 always sandwiched between the front wall 21 and the accommodating chamber D, and a side edge 23 is provided between the front wall 21 and the side wall 22.

The hinge assembly 30 is configured to: when the first rotating shaft P1 is actuated, a first distance is formed between the first rotating shaft P1 and the front end surface 103 of the case 10, and when the second rotating shaft P2 is actuated, a second distance is formed between the second rotating shaft P2 and the front end surface 103 of the case 10, and the second distance is greater than the first distance.

In addition, when the first rotation axis P1 is operated, a third distance is formed between the first rotation axis P1 and the outer side surface 13 of the casing 10, and when the second rotation axis P2 is operated, a fourth distance is formed between the second rotation axis P2 and the outer side surface 13 of the casing 10, and the fourth distance is smaller than the third distance.

Here, the "first rotation axis P1 is actuated" means that the first rotation axis P1 is in an operating state, that is, the second hinge member 32 rotates together with the slide piece 40 with respect to the first hinge member 31, and similarly, the "second rotation axis P2 is actuated" means that the second rotation axis P2 is in an operating state, that is, the second hinge member 32 rotates with respect to the slide piece 40.

Note that, the distance is a distance between the first and second rotation axes P1 and P2 and the front end surface 103 and the outer side surface 13 of the box 10 when the hinge assembly 30 moves to a certain position, and is not a distance in the closed state.

The concrete description is as follows:

in practice, in order to improve the insertion effect, it is preferable that the refrigerator 100 is completely inserted into the cabinet 200, and the refrigerator 100 is a free-insertion type refrigerator, that is, the front end 201 of the cabinet 200 is located on the same plane with the front wall 21 of the door 20 far from the cabinet 10, or the front wall 21 of the door 20 does not protrude out of the front end 201 of the cabinet 200 at all.

In the prior art, all refrigerators are single-shaft refrigerators, and a certain distance needs to be kept between a rotating shaft of the refrigerator and a side wall and a front wall of the refrigerator, so that a sufficient space can be provided to satisfy foaming or other processes, that is, the rotating shaft of the existing refrigerator is approximately located at a position of a single-shaft P3 in fig. 5, in this case, after the single-shaft refrigerator is embedded into a cabinet 200, since an edge 203 of the cabinet 200, which is clamped between a front end 201 and an inner wall 202, is arranged corresponding to a side edge 23 of a door 20, when the door 20 is opened, the side edge 23 interferes with the door 20 to limit a maximum opening angle of the door 20, and in order to ensure normal opening of the door 20, a common method in the prior art is to increase a distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, the distance needs to be approximately 10cm, and the embedding effect is seriously affected, and the limited space is not beneficial to reasonable utilization of the space.

Referring to fig. 5, the shaded area represents the door 20 in the closed state, when the door 20 is in the opening process, if the door 20 always rotates around the uniaxial axis P3 as the central axis (i.e. the prior art), referring to the dotted door 20 'in fig. 5, since the uniaxial axis P3 is close to the front end surface 103, i.e. the uniaxial axis P3 is far away from the front end 201 of the cabinet 200, when the door 20' is opened to a certain angle, the edge 203 of the cabinet 200 interferes with the door 20 'to limit the maximum opening angle of the door 20'.

In the present embodiment, the door body 20 rotates about the first rotating axis P1, specifically, the second hinge member 32 and the sliding sheet 40 rotate together with the first hinge member 31 by a certain angle, and along with the change of the positions of the second hinge member 32 and the sliding sheet 40, the relative position of the second rotating axis P2 to the cabinet 10 also changes, the second rotating axis P2 gradually gets away from the front end surface 103, that is, the second rotating axis P2 gradually moves toward the front end 201 of the cabinet 200, at this time, the door body 20 rotates about the second rotating axis P2 at the current position as the central axis, because the second rotating axis P2 at this time gets away from the front end surface 103 of the cabinet 10 compared to the first rotating axis P1, referring to the solid line door body 20 in fig. 5, the interference effect of the cabinet 200 edge 203 to the door body 20 is greatly reduced, and the cabinet 200 edge 203 interferes with each other when the door body 20 is opened to a larger angle, so that the maximum opening angle of the door body 20 is greatly increased.

That is to say, in the embodiment, the door body 20 is switched to rotate around the second rotation axis P2 after being opened to a certain angle, so that the maximum opening angle of the door body 20 can be effectively increased on the premise that the refrigerator 100 is freely embedded into the cabinet 200, the user can operate the refrigerator 100 conveniently, and the user experience can be greatly improved.

In addition, in the embodiment, the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100 does not need to be increased, the refrigerator 100 can be connected with the cabinet 200 in a seamless manner, and the embedding effect is greatly improved.

In addition, while the second rotation axis P2 of the present embodiment gradually moves toward the direction close to the front end 201 of the cabinet 200, the second rotation axis P2 also gradually moves close to the inner wall 202 of the cabinet 200, that is, when the door 20 rotates around the second rotation axis P2 as the central axis, the second rotation axis P2 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first rotation axis P1, so that the maximum opening angle of the door 20 can be increased, the door 20 can be away from the box 10 to increase the opening degree of the box 10, and the opening and closing of the racks, drawers, and the like in the box 10, or the taking and placing of the articles can be facilitated.

Of course, the second rotation axis P2, which is finally used as the central axis, may be located at other positions, for example, when the door 20 rotates around the second rotation axis P2, the second rotation axis P2 is closer to the front end 201 of the cabinet 200 than the first rotation axis P1, and the second rotation axis P2 is farther away from the inner wall 202 of the cabinet 200 than the first rotation axis P1.

It can be understood that the slide sheet 40 controls the switching sequence of the first hinge member 31 and the second hinge member 32 during the opening and closing processes of the door 20, so as to effectively prevent the door 20 from interfering with the cabinet 200 during the opening and closing processes.

In this embodiment, with reference to fig. 2 to 5, the hinge assembly 30 further includes a first receding groove 323 communicating with the third groove 321 and a second receding groove 324 communicating with the fourth groove 322, when the second hinge element 32 moves relative to the sliding piece 40, the first shaft 311 moves in the first receding groove 323, and the second shaft 312 moves in the second receding groove 324.

The first and second receding grooves 323 and 324 are both arc grooves, and the central axis of the arc groove is the second rotation axis P2.

Here, the second hinge element 32 and the sliding piece 40 are substantially matched through two parts, one part is the connection of the rotating element 50, the other part is the first slot 401 and the third slot 321 which are matched with each other, and the second slot 402 and the fourth slot 322 which are matched with each other, wherein, since the central axis when the third slot 321 and the fourth slot 322 are rotated is the first rotating axis P1, and the central axis when the rotating element 50 is rotated is the second rotating axis P2, the second hinge element 32 cannot be rotated simultaneously with the first rotating axis P1 and the second rotating axis P2 which are not in accordance with each other, that is, when the first shaft body 311 rotates in the third slot 321 (or the second shaft body 312 rotates in the fourth slot 322), the rotating element 50 cannot drive the second hinge element 32 to rotate relative to the sliding piece 40, that is, the second hinge element 32 and the sliding piece 40 are stationary relative to each other.

Specifically, when the hinge assembly 30 is in a process of being opened from a closed state to the first opening angle α 1, the first shaft 311 is located in the third slot 321 (or the second shaft 312 is located in the fourth slot 322), and due to the restriction effect of the first shaft 311 on the third slot 321, the second hinge 32 cannot rotate relative to the sliding piece 40 with the second rotation shaft P2 as a central axis, that is, the second hinge 32 and the sliding piece 40 are relatively stationary, at this time, the second hinge 32 and the sliding piece 40 can rotate together relative to the first hinge 31 through the movement of the first shaft 311 in the first slot 401 and the third slot 321 (or the movement of the second shaft 312 in the second slot 402 and the fourth slot 322), until the first shaft 311 is limited in the first slot 401 and/or the second shaft 312 is limited in the second slot 402, at this time, the sliding piece 40 cannot continue to rotate relative to the first hinge 31, and the first hinge 31 and the sliding piece 40 are locked with each other.

Then, when the hinge assembly 30 is in the process of continuously opening from the first opening angle α 1 to the second opening angle α 2, since the hinge assembly 30 further has the first receding groove 323 communicating with the third slot body 321 and the second receding groove 324 communicating with the fourth slot body 322, the first shaft body 311 moves in the first receding groove 323 with the second rotating shaft P2 as a central axis, and the second shaft body 312 moves in the second receding groove 324 with the second rotating shaft P2 as a central axis, the second hinge element 32 can be driven to rotate relative to the sliding piece 40.

It is understood that in other embodiments, other structures may be added to keep the second hinge element 32 and the slide 40 relatively stationary during the opening process from the closed state to the first opening angle α 1.

In the present embodiment, the second rotation axis P2 is a fixed axis, and the second hinge member 32 is pivoted relative to the slide plate 40 about the second rotation axis P2.

The second rotation axis P2 may be a virtual axis or a physical axis, which may be determined according to actual conditions.

In the present embodiment, with reference to fig. 2 to fig. 5, the rotating assembly 50 includes a third shaft 403 and a circular hole 325 between the sliding piece 40 and the second hinge element 32, and the third shaft 403 rotates in the circular hole 325 as the second rotating shaft P2.

Here, the second rotation axis P2 is a solid axis, the third axis 403 is located on one side of the sliding piece 40 close to the second hinge element 32, the circular hole 325 is located on the second hinge element 32, when the second hinge element 32 rotates relative to the sliding piece 40, the third axis 403 rotates in place in the circular hole 325, the first axis 311 slides in the first recess 323, and the second axis 312 slides in the second recess 324.

In addition, the rotating assembly 50 further includes a protrusion 326 and a sliding slot 404 located between the sliding piece 40 and the second hinge 32, and the protrusion 326 slides in the sliding slot 404 around the second rotating shaft P2 as a central axis.

At this time, when the second hinge element 32 rotates relative to the sliding piece 40, the third shaft 403 rotates in the circular hole 325, and the protrusion 326 slides in the sliding slot 404 around the second rotation axis P2, so as to improve the stability of the second hinge element 32 rotating relative to the sliding piece 40.

In addition, when the protrusion 326 slides in the sliding slot 404 to the end of the sliding slot 404 (i.e. when the protrusion 326 slides to the limit position), the first hinge 32 cannot rotate relative to the sliding piece 40, i.e. the maximum opening angle of the door 20 can be controlled by the length of the sliding slot 404, but not limited thereto.

In other embodiments, the rotating element 50 may not include the third shaft 403 and the circular hole 325, i.e., the second rotating shaft P2 is a virtual shaft.

That is, the rotating element 50 may only include the third shaft 403 and the circular hole 325, but not the protrusion 326 and the sliding groove 404, and the second rotating axis P2 is a solid axis at this time, or the rotating element 50 may only include the protrusion 326 and the sliding groove 404, but not the third shaft 403 and the circular hole 325, and the second rotating axis P2 is a virtual axis at this time, or the rotating element 50 may also include the protrusion 326, the sliding groove 404, the third shaft 403 and the circular hole 325, and the second rotating axis P2 is a solid axis at this time.

In the present embodiment, the protrusion 326 is located on the second hinge member 32, the protrusion 326 is a rib 326, the slide groove 404 is located on the slide piece 40, and the slide groove 404 penetrates the first slot 401 and/or the second slot 402.

Here, the rib 326 is an arc-shaped rib having a certain length, the sliding groove 404 is an arc-shaped groove having the second rotation axis P2 as a central axis, and the "sliding groove 404 penetrates the first groove 401 and/or the second groove 402" means that an extending track of the sliding groove 404 is communicated with the first groove 401 and/or the second groove 402, and the rib 326 can slide in the sliding groove 404 and enter the first groove 401 and/or the second groove 402.

When the sliding groove 404 penetrates through the first groove 401, the protruding rib 326 moves in the sliding groove 404 and penetrates through the first groove 401, the protruding rib 326 is matched with the first groove 401 to limit the first shaft 311, specifically, the protruding rib 326 is matched with the end of the first groove 401 to limit the first shaft 311, and the protruding rib 326 is tangent to the outer contour of the first shaft 311.

In other embodiments, with reference to fig. 6 to 18, the first shaft 311 has a first notch 3111 matching with the rib 326, and when the rib 326 slides to the first slot 401, the rib 326 passes through the first notch 3111 to directly limit the first shaft 311.

When the sliding groove 404 penetrates through the second groove 402, the rib 326 moves in the sliding groove 404 and penetrates through the second groove 402, the rib 326 is matched with the second groove 402 to limit the second shaft 312, specifically, the rib 326 is matched with the end of the second groove 402 to limit the second shaft 312, and the rib 326 is tangent to the outer contour of the second shaft 312.

In other embodiments, the second shaft 312 has a second notch 3121 matching with the rib 326, and when the rib 326 slides to the second groove 402, the rib 326 passes through the second notch 3121 to directly limit the second shaft 312.

It can be understood that, when the door 20 is closed from the maximum opening angle, if the first shaft 311 and the second shaft 312 are not limited at this time, the first shaft 311 may move back in the first slot 401 and the second shaft 312 may move back in the second slot 402, that is, the reset movement of the sliding piece 40 may be earlier than the reset movement of the second hinge piece 32, so that there is a risk that the movement track of the door 20 when closed is not controlled.

In this embodiment, the first shaft 311 and/or the second shaft 312 are/is limited by the engagement of the protruding rib 326 and the sliding slot 404, so that when the door 20 is closed at the maximum opening angle, only when the first shaft 311 and the second shaft 312 are/is separated from the limitation of the protruding rib 326, the sliding piece 40 can rotate, that is, when the door 20 is closed at the maximum opening angle, the second hinge 32 is driven to reset by the movement of the protruding rib 326 in the sliding slot 404 until the protruding rib 326 is separated from the first slot 401 and/or the second slot 402, the third slot 321 is overlapped with the first slot 401, the fourth slot 322 is overlapped with the second slot 402, and then the second hinge 32 and the sliding piece 40 are driven to reset together by the movement of the first shaft 311 in the first slot 401 and the third slot 321 and the movement of the second shaft 312 in the second slot 402 and the fourth slot 322.

In other embodiments, the protrusion 326 and the sliding groove 404 may have other structures.

For example, referring to fig. 17 and 18, the protrusion 326 is located on the second hinge 32, the protrusion 326 is a protruding pillar 326, the sliding slot 404 is located on the sliding piece 40, the sliding slot 404 and the first slot 401 are staggered, and the sliding slot 404 and the second slot 402 are staggered.

Of course, the rotating assembly 50 can be other than the protrusion 326 and the sliding slot 404, for example, the second hinge member 32 has an elastic member, and the sliding piece has a limiting hole, so that when the second hinge member 32 rotates relative to the sliding piece 40, the elastic member slides on the bottom of the sliding piece until the elastic member is limited in the limiting hole.

In the present embodiment, when the hinge assembly 30 is in the process of being opened from the closed state to the first opening angle α 1, that is, when the second hinge part 32 moves together with the slide piece 40 with respect to the first hinge part 31, the door body 20 includes a plurality of movement traces.

That is, in the whole opening process of the door 20, the motion trajectory of the door 20 is: the door 20 rotates in situ around the first rotation axis P1, and then the door 20 is switched to rotate in situ around the second rotation axis P2.

In the first movement path, the second shaft 312 and the second slot 402 may be omitted, and the door 20 is driven to rotate in situ around the first rotation axis P1 only by the rotation in situ of the first shaft 311 in the first slot 401.

Referring to fig. 20, in the second motion trajectory, the first slot 401 and the second slot 402 are both long, and when the hinge assembly 30 is opened from the closed state to the first opening angle α 1, the second shaft 312 moves in the second slot 402 to drive the first shaft 311 to move in the first slot 401, and the door 20 generates a translation amount relative to the box 10.

Here, the "door 20 generates a translation amount with respect to the refrigerator body 10" means that the door 20 simultaneously has a translation amount in the process of rotating with respect to the refrigerator body 10, and when corresponding to a refrigerator, the translation amount means a horizontal movement amount, that is, the door 20 generates a movement amount in a horizontal direction with respect to the refrigerator body 10 in addition to the rotation of the door 20 with respect to the refrigerator body 10.

That is, in the whole opening process of the door 20, the motion trajectory of the door 20 is: the door body 20 rotates and translates about the first rotation axis P1, and then the door body 20 is switched to rotate about the second rotation axis P2.

Next, various specific examples of the translation of the door body 20 will be described.

That is, the door 20 moves a certain distance in a direction away from the cabinet 200, so as to prevent the door 20 from interfering with the cabinet 200 during the initial opening process.

Here, the door 20 includes a front wall 21 distant from the housing chamber D and a side wall 22 interposed between the front wall 21 and the housing chamber D all the time, and the initial position A1 is distant from the front wall 21 and the side wall 22 as compared to the first stop position A2.

In a second specific example, referring to fig. 21, the first slot 401 includes an initial position A1 and a first stop position A2, the second slot 402 includes a first section L1 and a second section L2 connected to each other, when the hinge assembly 30 is in the process of opening from the closed state to the first intermediate opening angle α 11, the first shaft 311 is kept at the initial position A1, the second shaft 312 moves in the first section L1 with the first shaft 311 as the center axis, when the hinge assembly 30 is in the process of continuing to open from the first intermediate opening angle α 11 to the first opening angle α 1, 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 the door 20 moves from the pivot side P toward the accommodating chamber D.

That is, the door 20 rotates in situ at a certain angle and then moves a certain distance in the direction away from the cabinet 200, so as to prevent the door 20 from interfering with the cabinet 200 during the initial opening process.

Here, in the side-by-side refrigerator or the multi-door refrigerator having the vertical beam, having the left door and the right door arranged side by side, the door body 20 is rotated in situ at a certain angle to prevent the left door and the right door from interfering with each other.

When the hinge assembly 30' is in a closed state, one of the shaft bodies 311' extends into one of the groove bodies 401' and the limiting groove 321' which are overlapped with each other, and a central axis of the shaft body 311' when rotating does not coincide with a central axis of the rotating assembly 50' when rotating, wherein the other shaft body 312' extends into the other groove body 402', and the other shaft body 312' and the second hinge member 32' are arranged at intervals, the sliding piece 40' and the second hinge member 32' are relatively stationary, when the hinge assembly 30' is in an opening process, the second hinge member 32' and the sliding piece 40' move together relative to the first hinge member 31' until the shaft bodies 311', 312' are limited in the groove bodies 401', 402', and then the rotating assembly 50' drives the second hinge member 32' to move relative to the sliding piece 40 '.

Here, the "another shaft 312' is spaced apart from the second hinge member 32" means that the shaft 312' does not extend to the second hinge member 32 '.

In the present embodiment, the locking and unlocking between the first hinge element 31', the second hinge element 32' and the sliding piece 40' can be controlled by the structure of the hinge assembly 30', specifically, the mutual locking between the second hinge element 32' and the sliding piece 40' is controlled first, so that the second hinge element 32' and the sliding piece 40' are controlled to move together relative to the first hinge element 31', and then the unlocking between the second hinge element 32' and the sliding piece 40' is controlled, and the mutual locking between the first hinge element 31' and the sliding piece 40' is controlled, so that the second hinge element 32' is controlled to move relative to the sliding piece 40 '.

In a second specific example, with reference to fig. 50 to 51, when the hinge assembly 30 'is in the closed state, the limiting groove 322' and the second groove body 402 'overlap with each other, the second shaft body 312' extends into the second groove body 402 'and the limiting groove 322', the first shaft body 311 'extends only to the first groove body 401', and the first shaft body 311 'and the second hinge member 32' are spaced apart from each other.

Here, when the hinge assembly 30' is in the process of being opened from the closed state to the first opening angle α 1, since the first shaft 311', the central axis (i.e., the first rotating axis P1) of the second shaft 312' when rotating do not coincide with the central axis (i.e., the second rotating axis P2) of the rotating assembly 50' when rotating, when the second shaft 312' rotates in the limiting groove 322', the rotating assembly 50' cannot drive the second hinge 32' to rotate relative to the sliding piece 40', that is, the second hinge 32' and the sliding piece 40' are stationary.

Then, when the hinge assembly 30 'is in the process of continuously opening from the first opening angle α 1 to the second opening angle α 2, since the hinge assembly 30' further has the receding groove 324 'communicating with the limiting groove 322', the second hinge member 32 'can be driven to rotate relative to the sliding piece 40' by the second shaft 312 'moving in the receding groove 324' around the second rotation axis P2.

It can be seen that the second embodiment differs from the first embodiment in that: the second hinge part 32' of the second embodiment is provided with only one limiting groove, that is, the second hinge part 32' is provided with only the limiting groove 321' matched with the first shaft 311', or the limiting groove 322' matched with the second shaft 312', and at this time, the rotating component 50' can be matched to realize the relative rest of the second hinge part 32' and the sliding piece 40 '.
