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.

Also, terms such as "upper", "above", 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 "above" other elements or features would then be oriented "below" the other elements or features. Thus, the exemplary term "above" 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, a schematic diagram of a refrigerator 100 according to an embodiment of the present invention is shown.

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.

It is emphasized that the structure of the present embodiment is applicable not only to the refrigerator 100 with the hinge assembly 30, but also to other scenes, such as a cabinet, a wine chest, a wardrobe, and the like.

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.

Referring to fig. 2 to 13, the hinge assembly 30 includes a first hinge 31 fixed to the cabinet 10, a second hinge 32 fixed to the door 20, and a switching assembly 40 connecting the first hinge 31 and the second hinge 32.

The first hinge member 31 and the switching assembly 40 realize relative movement through the first shaft 311 and the first slot 411 which are matched with each other, and the first slot 411 includes a first free section S1.

The second hinge element 32 and the switching assembly 40 realize relative movement through the second

shaft body groups

321 and 322 and the second

slot body groups

421 and 422 which are matched with each other, the second

shaft body groups

321 and 322 include a third shaft body 321 and a fourth shaft body 322, the second

slot body groups

421 and 422 include a third free section 421, a fourth free section 4221 and a limit section 4222, the third free section 421 includes an initial position B1 and a pivot position B2 which are arranged oppositely, and the fourth free section 4221 includes a moving section M1 and a rotating section M2 which are connected in sequence.

When the door 20 is in the closed state (refer to fig. 14 to 17), the first shaft 311 is located at the first free section S1, the fourth shaft 322 is located at the position-limiting section 4222 so that the switching assembly 40 limits the second hinge element 32, and the third shaft 321 is located at the start position B1.

When the door 20 is in the process of being opened from the closed state to the first opening angle α 1 (refer to fig. 18 to 21), the first shaft 311 rotates in situ in the first free section S1 to drive the door 20 to rotate in situ relative to the box 10.

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 (refer to fig. 22 to 25), the fourth shaft 322 is disengaged from the stopper 4222, the third shaft 321 is kept at the initial position B1, and the switching assembly 40 stops the first hinge 31.

When the door 20 is in the process of continuously opening from the second opening angle α 2 to the maximum opening angle α 3 (refer to fig. 26 to 33), the fourth shaft 322 moves in the moving section M1 to drive the third shaft 321 to move from the initial position B1 to the pivot position B2, the door moves from the pivot side P toward the accommodating chamber S, the third shaft 321 then rotates in place at the pivot position B2, the fourth shaft 322 moves in the rotating section M2 with the third shaft 321 as the center of circle, and the door 20 continues to rotate in place relative to the box 10.

Specifically, when the door 20 is in the process of continuing to open from the second opening angle α 2 to the first intermediate opening angle α 21 (refer to fig. 26 to fig. 29), the fourth shaft 322 moves in the moving segment M1 to drive the third shaft 321 to move from the initial position B1 to the pivot position B2, and the door moves from the pivot side P toward the accommodating chamber S.

Here, when the door 20 is in the process of continuing to open to the first intermediate opening angle α 21 at 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 is displaced along the first direction X relative to the refrigerator body 10, 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 offsets the portion of the door 20 protruding out of the refrigerator body 10 along the second direction Y during the rotation process, thereby preventing the door 20 from interfering with peripheral cabinets or walls and the like during the opening process, and being suitable for embedded cabinets or scenes with small space for accommodating the refrigerator 100.

When the door 20 is in the process of continuously opening from the first intermediate opening angle α 21 to the third opening angle α 3 (refer to fig. 30 to 33), the third shaft 321 is kept at the pivot position B2, the fourth shaft 322 moves at the rotation section M2 with the third shaft 321 as the center, and the door 20 continues to pivot with respect to the box 10.

In an example, with reference to fig. 2 to 6, a first matching portion 25 is disposed on the door 20, and a second matching portion 12 is disposed on the box 10, when the door 20 is in a closed state, the first matching portion 25 and the second matching portion 12 are engaged with each other, and when the door 20 is 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 matching portion 25 to disengage from the second matching portion 12.

Here, the door 20 rotates in place relative to the cabinet 10, that is, the door 20 only rotates without generating displacement in other directions, so that the phenomenon that the first engaging portion 25 cannot be separated from the second engaging portion 12 due to displacement in one direction of the door 20 can be effectively avoided.

The refrigerator 100 in the present embodiment may be a single-door refrigerator having the first and second engaging

portions

25 and 12, or a side-by-side refrigerator, a multi-door refrigerator, or the like having the first and second engaging

portions

25 and 12.

The door 20 includes a first door 206 and a second door 207 pivotally connected to the cabinet 10 and arranged side by side in a horizontal direction.

The refrigerator 100 further includes a vertical beam 80 movably connected to one side of the first door 206 close to the second door 207, and the first engaging portion 25 is disposed at the vertical beam 80.

Here, the vertical beam 80 is movably connected to the right side of the first door body 206, the vertical beam 80 and the first door body 206 may be connected by a return spring 81, and the vertical beam 80 rotates with respect to the first door body 206 centering on the axis in the vertical direction, in other words, the vertical beam 80 may rotate with respect to the first door body 206 by the action of the return spring 81 and be maintained at a predetermined position.

The first mating portion 25 is a projection 25 projecting upward from the vertical beam 80.

The second matching portion 12 is fixed on the box 10, for example, the second matching portion 12 is a groove 12 on the base 104, the base 104 is fixed on the top of the accommodating chamber S, one end of the groove 12 has a notch 121, the opening direction of the notch 121 faces forward, the bump 25 and the groove 12 are both arc-shaped, and the bump 25 enters or separates from the groove 12 through the notch 121 to realize mutual spacing and mutual separation of the bump 25 and the groove 12.

Of course, it is understood that the specific structure of the first and second engaging

portions

25 and 12 is not limited to the above description, that is, the first engaging portion 25 is not limited to the protrusion 25 at the vertical beam 80, the second engaging portion 12 is not limited to the groove 12 engaged with the protrusion 25, and the first and second engaging

portions

25 and 12 may be a structure engaged with other areas of the refrigerator 100.

In this example, the door 20 further includes a third door 208 and a fourth door 209 pivotally connected to the cabinet 10 and arranged side by side along a horizontal direction, the third door 208 is located below the first door 206, the fourth door 209 is located below the second door 207, and the refrigerator 100 further includes a drawer 300 located below the third door 208 and the fourth door 209.

Here, the accommodating chambers S corresponding to the first door body 206 and the second door body 207 are refrigerating chambers, that is, the refrigerating chambers are of a split door structure; the third door body 208 and the fourth door body 209 correspond to two independent variable temperature chambers respectively; drawer 300 is a freezer drawer.

It should be noted that the refrigerator 100 includes a fixed beam fixed inside the refrigerator body 10 and used for separating two temperature-changing chambers, and the third door body 208 and the fourth door body 209 can be matched with the fixed beam to achieve sealing, that is, at this time, no vertical beam needs to be arranged at the third door body 208 and the fourth door body 209.

In another example, referring to fig. 7 to 9, the box 10 ' includes a fixed beam 70 ' dividing the accommodating chamber S into a first compartment S3 and a second compartment S4, the door 20 ' includes a first door 204 ' corresponding to the first compartment S3 ' and a second door 205 ' corresponding to the second compartment S4, when the door 20 ' is in a closed state, the first door 204 ' and the second door 205 ' both contact the fixed beam 70 ', and when the door 20 is in a 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 separate the door 20 ' from the fixed beam 70 '.

Here, the first door 204 'and the second door 205' may be provided with door seals at a side close to the cabinet 10 ', and when the door 20' is in a closed state, the door seals contact with the contact surface 71 'of the fixed beam 70' to completely close the door 20 ', so as to prevent cold air in the cabinet 10' from leaking.

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 situ relative to the box 10 ', that is, the door 20' only rotates without generating displacement in other directions, so that the problem that the door 20 'cannot be normally opened due to the displacement in a certain direction of the door 20' can be effectively avoided.

At this time, if the first door 204 'generates a displacement in the horizontal direction when being opened, the first door 204' and the second door 205 'may generate mutual interference to cause that the first door 204' and the second door 205 'cannot be normally opened, and the first door 204' and the second door 205 'rotate in situ when the refrigerator 100' of the embodiment is opened, so that the mutual interference between the adjacent first door 204 'and the second door 205' can be effectively avoided.

The opening size of the first upper slot 413 is matched with that of the first shaft 311, and the opening size of the first lower slot 414 is larger than that of the first upper slot 413.

Here, the first upper groove 413 is circular, and the first lower groove 414 is oval, but not limited thereto.

In the present embodiment, the first switching member 401 is closer to the first hinge member 31 than the second switching member 402, that is, the first hinge member 31, the first switching member 401, the second switching member 402, and the second hinge member 32 are stacked in this order.

Referring to fig. 13, the hinge assembly 30 further includes a first rivet tab 4111 and a second rivet tab 4121, and when the first shaft 311 extends into the first slot 411, the first rivet tab 4111 is located below the second switch member 402 and is sleeved on the first shaft 311, so as to prevent the first shaft 311 from separating from the first slot 411.

The first switching member 401 and the second switching member 402 are coupled to each other through the fifth shaft 50.

Here, the first switch 401 and the second switch 402 are provided with a first through hole 4014 and a second through hole 4024, and an independent rivet is inserted as the fifth shaft body 50 through the first through hole 4014 and the second through hole 4024.

Specifically, the fifth shaft 50 includes a rivet post 51 and a rivet post gasket 52, the rivet post 51 has a larger end located below the second through hole 4024, the rivet post 51 has a smaller end extending to the second through hole 4024 and the first through hole 4014 in sequence, and the rivet post gasket 52 is located above the first through hole 4014 and is engaged with the rivet post 51 to lock the rivet post 51.

In this way, the first switch 401 and the second switch 402 can be connected to each other, that is, the first switch 401 and the second switch 402 can move relatively, and the first switch 401 and the second switch 402 cannot be separated from each other.

It should be noted that the first through hole 4014 and the second through hole 4024 are matched with the fifth shaft 50, and the first switch member 401 rotates in place relative to the second switch member 402.

In another embodiment, a through hole may be formed in one of the first switching member 401 and the second switching member 402, and the fifth shaft 50 is disposed in the other, so that the first switching member 401 and the second switching member 402 are coupled with each other by the engagement of the fifth shaft 50 and the through hole, but not limited thereto.

In addition, the first switching member 401 includes a third shaft body 321, the second switching member 402 has a through hole 4026, the third shaft body 321 extends to the third slot 421 through the through hole 4026, the second switching member 402 includes a fourth shaft body 322, and the fourth shaft body 322 extends to the fourth slot 422.

Here, the size of the through hole 4026 may be larger than that of the third shaft 321, such that the third shaft 321 can move in the through hole 4026, and when the first switching member 401 and the second switching member 402 move relatively, the through hole 4026 and the third shaft 321 can be prevented from interfering with each other.

That is, the third shaft 321 and the fourth shaft 322 are located in different switching elements in this embodiment, but the invention is not limited thereto.

Here, the first through hole 4014 may be formed only by forming the groove holes in the first slide piece 4012 and the first bushing 4013, that is, the first through hole 4014 does not penetrate the first lining 4011, and at this time, the fifth shaft body 50 extends from below the first switch 401 to the first through hole 4011, and the first lining 4011 may shield the first through hole 4014 and the fifth shaft body 50, thereby improving the appearance.

The outer contours of the second gasket 4021, the second sliding piece 4022 and the second bushing 4023 are matched, the second gasket 4021 and the second bushing 4023 are matched with each other to clamp the second sliding piece 4022 therebetween, and the second gasket 4021, the second sliding piece 4022 and the second bushing 4023 are all required to be provided with slots to form the first lower slot 414, the second lower slot 416 and the second through hole 4024 in a matched manner.

Here, the second penetration hole 4024 may be formed only by forming the groove holes in the second pad 4021 and the second slide 4022, that is, the second penetration hole 4024 does not penetrate the second bushing 4023, in this case, the fifth shaft body 50 extends from below the second bushing 4023 to the second penetration hole 4024 and the first penetration hole 4011, and the second bushing 4023 may shield the second penetration hole 4024 and the fifth shaft body 50, thereby improving the appearance.

At this time, one end of the rivet pin 51 of the fifth shaft 50 may be limited in the second bushing 4023, so as to further improve the matching effect of the second lining 4021, the second slide 4022 and the second bushing 4023.

Here, "the first decorative piece 4015 and the second decorative piece 4025 are separated from each other" means that the first decorative piece 4015 and the second decorative piece 4025 are independent from each other, and when the first switch 401 and the second switch 402 move relatively, the first decorative piece 4015 and the second decorative piece 4025 also move relatively.

In addition, the first decorative sheet 4015 of the present embodiment is shaped like a "door", that is, the first decorative sheet 4015 covers only three sides of the first switch 401, so as to facilitate the assembly of the first decorative sheet 4015, and the three sides can be provided with snap structures to realize the engagement with the first decorative sheet 4015, and the width of the first decorative sheet 4015 is substantially equal to the sum of the thicknesses of the first lining 4011, the first slide piece 4012, and the first bush 4013 in the stacking direction of the first switch 401 and the second switch 402.

The first decorative sheet 4015 and the second decorative sheet 4025 may be made of abs (acrylonitrile butadiene styrene) plastic.

Next, a specific operation flow of the hinge assembly 30 will be described.

In the present embodiment, the box 10 includes an outer side surface 13 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 21 far from the accommodating chamber S and a side wall 22 always interposed between the front wall 21 and the accommodating chamber S, and a side edge 23 is provided between the front wall 21 and the side wall 22.

Referring to fig. 14 to 17, when the door 20 is in the closed state, the first switching element 401 and the second switching element 402 are stationary relative to each other, the first shaft 311 is located at the first free section S1, the fourth shaft 322 is located at the position-limiting section 4222, so that the switching assembly 40 limits the second hinge element 32, and the third shaft 321 is located at the start position B1.

Specifically, the outer side surface 13 and the side wall 22 are located on the same plane, so that smoothness in appearance can be ensured, the appearance is more attractive, and the door body 20 can be conveniently mounted, but not limited thereto.

Here, when the door 20 is in the closed state, the third shaft 321 is located at the start position B1, the fourth shaft 322 is located in the stopper 4222, the distance between the third shaft 321 and the fourth shaft 322 remains unchanged, the third shaft 321 is located at the first switching element 401, the fourth shaft 322 is located at the second switching element 402, and the first switching element 401 and the second switching element 402 are relatively stationary under the common limit of the third shaft 321 and the fourth shaft 322.

Referring to fig. 18 to 21, when the door 20 is in the process of being opened from the closed state to the first opening angle α 1, the first switch element 401 and the second switch element 402 are relatively stationary, the overlapping portion of the first upper slot body 413 and the first lower slot body 414 forms a first free section S1, the first shaft body 311 rotates in situ in the first free section S1, the recessed portion 4016 abuts against the bump 314 to limit the first hinge element 31 by the switch assembly 40, and the door 20 rotates in situ relative to the box 10.

Here, when the door body 20 is in the closed state, the bump 314 is located in the recessed portion 4016, the first stopper surface 3141 is away from the second stopper surface 4017, when the door body 20 is in the process of opening from the closed state to the first opening angle α 1, the first hinge part 31 is fixed to the box 10, the door body 20 drives the switching component 40 to move together relative to the first hinge part 31, the bump 314 moves in the recessed portion 4016, the first stopper surface 3141 and the second stopper surface 4017 gradually approach until the first stopper surface 3141 abuts against the second stopper surface 4017, at this time, the first switching part 401 cannot rotate relative to the first hinge part 31 any more, that is, the switching component 40 realizes locking of the first hinge part 31, and the rotation angle of the door body 20 when the first stopper surface 3141 abuts against the second stopper surface 4017 can be controlled by controlling the size, shape and the like of the bump 314 and the recessed portion 4016.

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.

It should be noted that, when the door body 20 is opened from the closed state to the first opening angle α 1, the fourth shaft body 322 is always limited by the limit section 4222, so that the switching assembly 40 limits the second hinge element 32.

With reference to fig. 22 to 25, 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 first switching element 401 and the second switching element 402 move relatively to separate the fourth shaft 322 from the stopper 4222, and the third shaft 321 is maintained at the start position B1.

Specifically, when the first switching element 401 and the second switching element 402 move relatively, the distance between the third shaft 321 located on the first switching element 401 and the fourth shaft 322 located on the second switching element 402 changes, the third shaft 321 is always located at the start position B1, and the fourth shaft 322 moves from the position-limiting section 4222 to the fourth free section 4221, i.e., the fourth shaft 322 is separated from the position-limiting section 4222.

It should be noted that the locking of the first hinge member 31 is not limited to the cooperation of the protrusion 314 and the recess 4016, and in other embodiments, the first hinge member 31 may be locked by another structure, for example, the first shaft 311 is locked to lock the first hinge member 31, specifically, a locking section may be disposed at the first groove 411, and the first shaft 311 may be locked when the first shaft 311 rotates to the locking section, or the first switching member 401 and the second switching member 402 move relative to each other to form a locking section between the first upper groove 413 and the first lower groove 414, where the locking section may be used to lock the first shaft 311.

Referring to fig. 26 to fig. 29, when the door 20 is in the process of opening from the second opening angle α 2 to the first intermediate opening angle α 21, the first switch element 401 and the second switch element 402 are stationary, the fourth shaft 322 moves in the moving segment M1 to drive the third shaft 321 to move from the start position B1 to the pivot position B2, and the door moves from the pivot side P toward the accommodating chamber S.

Here, the side edge 23 moves to a side of the outer side surface 13 close to the accommodating chamber S, that is, the hinge assembly 30 drives the side edge 23 to move toward the side close to the accommodating chamber S, so that interference with a surrounding cabinet or wall due to the side edge 23 protruding out of the outer side surface 13 can be avoided during the opening 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 23 moves toward the side close to the accommodating chamber S into the plane of the outer side surface 13, and then the hinge assembly 30 drives the side edge 23 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 23 does not protrude out of the corresponding outer side surface 13, the side edge 23 is as close as possible to the outer side surface 13, 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, referring to fig. 29, a connection line between the start position B1 and the pivot position B2 is parallel to the moving segment M1, that is, the fourth shaft 322 translates in the moving segment M1 to drive the third shaft 321 to translate from the start position B1 to the pivot position B2, and at this time, the door 20 translates from the pivot side P toward the accommodating chamber S.

Referring to fig. 30 to 33, when the door 20 is in the process of continuously opening from the first intermediate opening angle α 21 to the maximum opening angle α 3, the first switching element 401 and the second switching element 402 are relatively stationary, the third shaft 321 is maintained at the pivot position B2, the fourth shaft 322 moves in the rotation section M2 around the third shaft 321, and the door 20 continuously rotates in place relative to the box 10.

It can be seen that, in the present embodiment, the switching assembly 40 unlocks and locks the first hinge member 31 and the second hinge member 32, so that the sequential switching of the first hinge member 31 and the second hinge member 32 can be effectively controlled, and the door body 20 can be stably opened.

In this embodiment, referring to fig. 34 and 35, the first switch 401 includes a first stopper 4018, the second switch 402 includes a second stopper 4027 cooperating with the first stopper 4018, and when the door body 20 is in the process of being closed from the second opening angle α 2 to the first opening angle α 1, the second switch 402 restricts the movement of the first switch 401 by the cooperation of the second stopper 4027 and the first stopper 4018.

Specifically, the first stopping portion 4018 is a groove portion 4018 located on the first switching member 401, the second stopping portion 4027 is a protrusion 4027 located on the second switching member 402, one end of the groove portion 4018 is a stopping end 4019, when the door body 20 is opened from the closed state to the first opening angle α 1, the first switching member 401 and the second switching member 402 are relatively stationary, the protrusion 4027 is maintained on one side of the groove portion 4018 away from the stopping end 4019, when the door body 20 is opened from the first opening angle α 1 to the second opening angle α 2, the first switching member 401 and the second switching member 402 relatively move, the protrusion 402 moves towards one side close to the stopping end 4019 in the groove portion 4018 until the protrusion 402 abuts against the stopping end 4019, and the first switching member 401 and the second switching member 402 relatively stationary.

It can be understood that, during the opening process of the door 20, the relative movement between the first switching member 401 and the second switching member 402 can be controlled by other structures, for example, the first switching member 401 and the second switching member 402 end the relative movement by the abutting of the groove bodies on the first switching member 401 and the second switching member 402 with the first shaft body 311 and the third shaft body 321, at this time, the first switching member 401 and the second switching member 402 keep relatively stationary and in a mutually staggered state, preferably, when the first switching member 401 and the second switching member 402 end the relative movement, the protrusion 402 just abuts against the stopping end 4019, but not limited thereto.

The interaction between the protrusion 402 and the groove 4018 mainly plays a role in the closing process of the door 20, and in actual operation, when the door 20 is in the process of closing from the second opening angle α 2 to the first opening angle α 1, because the protrusion 402 abuts against the stop end 4019, the first switching member 401 cannot rotate under the condition that the second switching member 402 does not rotate, that is, in the process, the rotation of the first switching member 401 is certainly later than the rotation of the second switching member 402, and after the first switching member 401 and the second switching member 402 are overlapped, the first switching member 401 and the second switching member 402 are relatively stationary, and then the first switching member 401 and the second switching member 402 move together relative to the first shaft 311 until the door 20 is closed.

It can be understood that the closing process of the door 20 and the opening process of the door 20 are processes in reverse order, and the switching order of the first hinge member 31 and the second hinge member 32 in the opening and closing processes of the door 20 can be effectively controlled by the unlocking and locking actions of the switching assembly 40 on the first hinge member 31 and the second hinge member 32.

In the present embodiment, a fourth distance is formed between the center of the third shaft 312 and the side edge 23, a fifth distance is formed between the center of the third shaft 312 and the front wall 21, and a sixth distance is formed between the center of the third shaft 312 and the side wall 22, and when the door 20 is opened from the second opening angle α 2 to the maximum opening angle α 3, the fourth distance, the fifth distance, and the sixth distance all decrease and then remain unchanged.

It should be noted that the distance variation is not limited to the above description, for example, when the door 20 is in the process of opening from the second opening angle α 2 to the first intermediate opening angle α 21, the fifth distance is always kept unchanged, and the fourth distance and the sixth distance both tend to decrease and then increase and then keep unchanged.

The motion trajectory of the present invention is not limited to the above description, and is a schematic view of a hinge assembly according to another embodiment of the present invention with reference to fig. 36 to 40, for convenience of description, the same or similar structures are numbered the same or similar structures, the difference between the present embodiment and the previous embodiment is mainly at the second hinge element 32 ', and the description of the first hinge element 31' can refer to the previous embodiment, and will not be repeated herein.

The second hinge member 32 'includes a third slot 421' and a fourth slot 422 ', the third slot 421' includes a start position B1 'and a pivot position B2' that are oppositely disposed, and the fourth slot 422 'includes a position-limiting segment 4222', a moving segment M1 'and a rotating segment M2' that are sequentially connected.

Here, the third slot 421 ' is oval, the moving section M1 ' is arc-shaped, and the stopper 4222 ', the moving section M1 ' and the rotating section M2 ' are not overlapped with each other.

It should be noted that, the "third slot 421 ' is oval" means that the third shaft 321 ' moves along a straight line in the third slot 421 ', and the "moving section M1 ' is arc-shaped" means that the fourth shaft 322 ' moves along an arc in the moving section M1 ', that is, the fourth shaft 322 ' rotates in the moving section M1 ' to drive the third shaft 321 ' to move from the initial position B1 ' to the pivotal position B2 '.

Specifically, when the door 20 is in the closed state and the door 20 is in the process of being opened from the closed state to the first opening angle α 1, referring to fig. 37, the first switching member 401 ' and the second switching member 402 ' are relatively stationary, the third shaft 321 ' is located at the start position B1 ', and the fourth shaft 322 ' is located at the position-limiting segment 4222 ' to limit the second hinge 32 '.

When the door 20 is in the process of continuing to open from the first opening angle α 1 to the second opening angle α 2, referring to fig. 38, the first switching member 401 'and the second switching member 402' move relatively to separate the fourth shaft 322 'from the stopper 4222', and the third shaft 321 'is maintained at the start position B1'.

When the door 20 is in the process of continuing to open from the second opening angle α 2 to the first intermediate opening angle α 21, referring to fig. 39, the first switching element 401 ' and the second switching element 402 ' are stationary, the fourth shaft 322 ' rotates in the moving segment M1 ' to drive the third shaft 321 ' to translate from the start position B1 ' to the pivot position B2 ', and the door moves from the pivot side P toward the accommodating chamber S.

When the door 20 is in the process of continuously opening from the first intermediate opening angle α 21 to the maximum opening angle α 3, referring to fig. 40, the first switching element 401 ' and the second switching element 402 ' are relatively stationary, the third shaft 321 ' is maintained at the pivot position B2 ', the fourth shaft 322 ' moves in the rotation section M2 ' around the third shaft 321 ', and the door 20 continues to pivot with respect to the box 10.

For other descriptions of this embodiment, reference may be made to the previous embodiment, which is not described herein again.

The third and

fourth grooves

421 and 422 of the present invention may have other shapes, and only the movement locus of the present invention is required to be ensured.

The first shaft 311 and the third shaft 321 of the present invention are staggered from each other, so that the present invention can be applied to a built-in cabinet or a scene where a space for accommodating the refrigerator 100 is small.

Referring to fig. 41, a simple schematic diagram of the refrigerator 100 embedded in the cabinet 200 will be described.

In the present embodiment, the box 10 includes an opening 102 and a front end surface 103 disposed around the opening 102, the box 10 further includes an accommodating chamber S and an outer side surface 13 adjacent to the hinge assembly 30 and on an extension of a rotation path of the door 20, the door 20 includes a front wall 21 far from the accommodating chamber S and a side wall 22 interposed between the front wall 21 and the accommodating chamber S, and a side edge 23 is provided between the front wall 21 and the side wall 22.

Here, when the door 20 is in the process of being opened to the first opening angle α 1 in the closed state, the door 20 rotates around the first shaft 311, the first shaft 311 has a first distance from the front end surface 103, and when the door 20 is continuously opened from the second opening angle α 2 to the maximum opening angle α 3, the door 20 rotates around the third shaft 321, the third shaft 321 has a second distance from the front end surface 103, and the second distance is greater than the first distance, so that the maximum opening angle of the fully-embedded refrigerator 100 can be greatly increased.

In addition, a third distance is provided between the first shaft 311 and the outer side surface 13, and when the door 20 is in the process of being continuously opened from the second opening angle α 2 to the maximum opening angle α 3, a fourth distance is provided between the third shaft 321 and the outer side surface 13, and the fourth distance is smaller than the third distance, so that the opening degree of the box 10 can be further increased.

The concrete description is as follows:

in some movement tracks of the refrigerator 100, the first shaft 311 and the third shaft 321 move relative to the door 20, and for simplicity, the door 20 is simply regarded as rotating with the first shaft 311 as a shaft, and then switching to rotate with the third shaft 321 as a shaft by the switching component 40.

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 the side wall and the front wall of the refrigerator, so that enough space can be provided for satisfying foaming or other processes, that is, the position of the rotation shaft of the conventional refrigerator is approximately at the position of the first shaft body 311 in fig 41, in this case, after the single-axis refrigerator is inserted into the cabinet 200, since the corner 203 of the cabinet 200 between the front end 201 and the inner wall 202 is disposed corresponding to the side edge 23 of the door body 20, when the door 20 is opened, the side edge 23 interferes with the door 20 to limit the maximum opening angle of the door 20, in order to ensure the normal opening of the door 20, the conventional method is to increase the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100, this gap needs to be roughly around 10cm, which seriously affects the embedding effect and is not good for the rational use of limited space.

Referring to fig. 41, a shaded area represents the door 20 in a closed state, when the door 20 is in an opening process, if the door 20 always rotates around the first shaft 311 (i.e. the prior art), referring to the dashed door 20 'in fig. 41, since the first shaft 311 is close to the front end surface 103, that is, the first shaft 311 is far away from the front end 201 of the cabinet 200, after 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 third shaft 321 is located on the first switching element 401, and in the opening process of the door 20, the switching assembly 40 moves relative to the first hinge element 31 and the second hinge element 32 to make the third shaft 321 gradually away from the front end surface 103, that is, the third shaft 321 gradually moves toward the direction close to the front end 201 of the cabinet 200, that is, the whole door 20 moves toward the direction away from the box 10, referring to the solid-line door 20 in fig. 41, the interference effect of the corner 203 of the cabinet 200 on the door 20 is greatly reduced, and the corner 203 of the cabinet 200 interferes with each other when the door 20 is opened to a larger angle, so that the maximum opening angle of the door 20 is greatly increased.

That is to say, in the embodiment, the door 20 can rotate around the third shaft 321 through the switching component 40, so that the maximum opening angle of the door 20 can be effectively increased on the premise that the refrigerator 100 is freely embedded into the cabinet 200, the refrigerator 100 can be conveniently operated by a user, and the user experience can be greatly improved.

In addition, in the present embodiment, the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100 does not need to be increased, the refrigerator 100 and the cabinet 200 can be connected seamlessly, and the insertion effect is greatly improved.

In addition, the switching assembly 40 of the present embodiment drives the third shaft 321 to gradually move toward the front end 201 of the cabinet 200, and simultaneously drives the third shaft 321 to gradually approach the inner wall 202 of the cabinet 200, that is, when the door 20 rotates about the third shaft 321, the third shaft 321 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first shaft 311, so as to increase the maximum opening angle of the door 20, and further make the door 20 away from the cabinet 10 to increase the opening degree of the cabinet 10, thereby facilitating the opening and closing of the racks, drawers, etc. in the cabinet 10, or facilitating the taking and placing of articles.

Of course, the third shaft 321, which is finally used as a rotation shaft, may be located at other positions, for example, when the door 20 rotates around the third shaft 321, the third shaft 321 is closer to the front end 201 of the cabinet 200 than the first shaft 311, and the third shaft 321 is farther away from the inner wall 202 of the cabinet 200 than the first shaft 311.

It can be understood that, the switching assembly 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 the present embodiment, the hinge assembly 30 located at different regions of the door body 20 has different structures, and the hinge assembly 30 is a hinge assembly 30 located between the upper portion of the door body 20 and the cabinet 10, and hereinafter, the hinge assembly 30' located between the lower portion of the door body 20 and the cabinet 10 will be briefly described with reference to fig. 42 and 43.

The lower hinge assembly 30' differs from the upper hinge assembly 30 in that: the first hinge part 31 ' of the hinge assembly 30 ' has a protrusion 313 ', the second hinge part 32 ' has a corresponding hook 323 ', the hook 323 ' is an elastic part, when the door 20 is in a closed state, the protrusion 313 ' acts on the hook 323 ' to deform, so that the door 20 is tightly matched with the box 10, and when the door 20 is in an opening state, the door 20 drives the hook 323 ' to move, and the hook 323 ' deforms to separate from the protrusion 313 '.

That is, when the door 20 is in the closed state, the protruding portion 313 'and the hook 323' are in interference fit, so that the closing effect of the door 20 is enhanced.

It should be noted that, since the switching component 40 'is connected between the first hinge member 31' and the second hinge member 32 ', the second hinge member 32' further includes an extension 324 'passing through the switching component 40' in the thickness direction, and the extension 324 'is connected to the hook 323', so that the hook 323 'is horizontally disposed and can be matched with the protrusion 313'.
