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, certain dimensions of structures or portions may be exaggerated relative to other structures or portions for convenience of illustration, and thus, are merely used to illustrate the basic structure of the subject matter of the present invention.

Referring to fig. 1 to 3, a schematic view of an embedded refrigerator 100 with a variable door rotation axis 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 further 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, and a direction of the receiving chamber S toward the outer side surface 13 is a first direction X.

The box 10 further includes a back 105 and an opening 102 disposed oppositely, and a front end surface 103 disposed around the opening 102, a direction of the opening 102 facing the back 105 is a second direction Y, the back 105 is a rear wall of the box 10, the opening 102 is a front end opening of the accommodating chamber S, the front end surface 103 is a front end surface of the accommodating chamber S, and the second direction Y is a direction from front to back of the box 10.

The door body 20 includes a front wall 21 distant from the storage chamber S and a side wall 22 interposed between the front wall 21 and the storage chamber S, and a side edge 23 is provided between the front wall 21 and the side wall 22.

The hinge assembly 30 includes a first hinge member 31 fixed to the body 10, a second hinge member 32 fixed to the door body 20, and a switching assembly 40 connecting the first hinge member 31 and the second hinge member 32.

The switching assembly 40 includes a first switching member 401 and a second switching member 402 that are matched with each other, 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 second hinge member 32 and the switching assembly 40 are installed in sequence as the first hinge member 31, the first switching member 401, the second switching member 402 and the second hinge member 32, and the first hinge member 31, the first switching member 401, the second switching member 402 and the second hinge member 32 are stacked in sequence, but not limited thereto.

When the door 20 is in the process of opening from the closed state to the first opening angle α 1, the first switching piece 401, the second switching piece 402 and the second hinge piece 32 are relatively stationary and move together relative to the first hinge piece 31, the door 20 rotates in place relative to the cabinet 10, when the door body 20 is in the process of continuing to open from the first opening angle alpha 1 to the second opening angle alpha 2, the first switching member 401 is stationary relative to the first hinge member 31, the second switching member 402 is stationary relative to the second hinge member 32 and moves together with the first switching member 401, the door body 20 moves away from the cabinet 10 in the first direction X, when the door body 20 is in the process of continuing to open from the second opening angle alpha 2 to the maximum opening angle alpha 3, the first hinge 31, the first switch 401 and the second switch 402 are relatively stationary, the second hinge 32 moves relative to the second switch 402, and the door 20 continues to pivot relative to the cabinet 10.

It can be seen that the switching assembly 40 connects the first hinge member 31 and the second hinge member 32 to enable the door 20 to switch the rotation axis in the opening process, specifically, the rotation axis of the door 20 that rotates in situ in the process of opening from the closed state to the first opening angle α 1 is different from the rotation axis of the door 20 that rotates in situ in the process of continuously opening from the second opening angle α 2 to the maximum opening angle α 3, so that the movement track of the door 20 can be changed by switching the rotation axis, so that the refrigerator 100 can adapt to the embedded application scenario, in addition, the door 20 in the embodiment moves away from the box 10 along the first direction X in the opening process, i.e., the door 20 moves away from the accommodating chamber S, so that the door 20 can move away from the box 10 along the first direction X as much as possible, thereby ensuring the opening degree of the box 10, and avoiding the drawer in the box 10, The rack and the like are interfered by the door body 20 and can not be opened.

In the present embodiment, a door seal 26 is provided on a side of the door 20 close to the cabinet 10, and the door seal 26 includes a side door seal 261 close to the outer side surface 13.

Here, the door seal 26 is annularly disposed on a side surface of the door body 20 close to the body 10, and the side door seal 261 is a door seal disposed closest to the hinge assembly 30 and in a vertical direction.

When the door 20 is in the closed state, the door seal 26 and the front end surface 103 contact each other.

Here, the door seal 26 and the front end surface 103 contact each other to achieve a sealing engagement between the door 20 and the cabinet 10, and generally, the sealing effect is improved by the pressing, magnetic attraction, and the like of the door seal 26.

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 hinge assembly 30 drives the side door seal 261 to move along the first direction X.

Here, the rotation of the door 20 drives the side door seal 261 to move in the opposite direction of the first direction X, and the hinge assembly 30 of the present embodiment drives the side door seal 261 to move in the first direction X, so that the movement amount of the side door seal 261 in the opposite direction of the first direction X can be effectively reduced, thereby preventing the side door seal 261 from obstructing the opening of the drawer, the rack, and the like in the box 10.

In the present embodiment, the door 20 includes a door center of gravity, and when the door 20 is in the process of being continuously opened from the first opening angle α 1 to the second opening angle α 2, the hinge assembly 30 drives the door 20 to move away from the cabinet 10 along the first direction X, and at the same time, the hinge assembly 30 drives the door center of gravity to move toward the cabinet 10.

Here, the gravity center of the door body is defined as a resultant point of gravity borne by each portion of the door body 20, the door body 20 has a heavy self-weight, and the door body 20 is selectively provided with a bottle seat, a dispenser, an ice maker and other components, so that the weight of the door body 20 is further increased to cause a risk of toppling over the whole refrigerator 100, and the hinge assembly 30 of the embodiment can drive the gravity center of the door body to move towards a direction close to the refrigerator body 10, thereby effectively preventing the toppling over of the refrigerator 100.

Specifically, the gravity center of the door body moves close to the refrigerator body 10 in the second direction Y, and at this time, the gravity center of the door body is close to the refrigerator body 10, so that the stability of the whole refrigerator 100 can be improved.

It should be noted that, during the opening process of the door 20 in the present embodiment, the hinge assembly 30 simultaneously drives the door 20 to move in the first direction X and the center of gravity of the door to move in a direction close to the refrigerator body 10, that is, simultaneously achieves the opening degree increase of the door 20 and the prevention of the refrigerator 100 from falling.

Referring to fig. 14 to 18, when the door 20 is in a closed state, the first switching element 401 and the second switching element 402 are relatively stationary, the first shaft 311 extends to the first upper slot 413, the third shaft 321 sequentially passes through the through hole 4026 and the third slot 421, the third shaft 321 is located at an initial position a1 and an initial position C1, the fourth shaft 322 is located at a rotation initial position D1 of the fourth slot 422, the first shaft 311 further extends to the first lower slot 414 and is located at a first end B1, and the fifth shaft 50 is located at a third end E1 of the fifth slot 417.

At this time, the first stopper surface 3141 of the first stopper portion 314 is away from the second stopper surface 4017 of the second stopper portion 4016.

The third engaging portion 405 is limited to the first engaging portion 315, that is, the third elastic element 4052 acts on the third boss 4051 to be limited to the first engaging portion 315, and at this time, the third engaging portion 405 and the first engaging portion 315 can be used as a closing element to assist in improving the closing effect of the door body 20.

The sixth engaging portion 404 is limited to the fourth engaging portion 4031, that is, the sixth elastic element 4042 acts on the sixth boss 4041 to limit to the fourth engaging portion 4031, at this time, the sixth engaging portion 404 and the fourth engaging portion 4031 can cooperate with each other to assist in realizing the relative rest of the first switch element 401 and the second switch element 42.

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.

Referring to fig. 19 to 23, 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 401, the second switch 402 and the second hinge 32 are relatively stationary and move together relative to the first hinge 31, and at this time, the first shaft 311 rotates in situ in the first upper groove 413 to drive the door 20 to rotate in situ relative to the box 10.

Here, when the door 20 is in the process of opening from the closed state to the first opening angle α 1, the first shaft body 311 is held at the first end B1 of the first lower slot body 414, the third shaft body 321 is held at the initial position a1 and the starting position C1, the fourth shaft body 322 is held at the rotation starting position D1, and the fifth shaft body 50 is held at the third end E1 of the fifth slot body 417.

Specifically, when the door 20 is in the closed state, the third shaft 321 is located at the initial position a1 and the initial position C1, the fourth shaft 322 is located at the rotation initial position D1, 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, 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, and since the fourth slot 422 is an arc slot with the pivot position C2 of the third slot 421 as the center of the circle, when the third shaft 321 is located at the initial position C1, the fourth shaft 322 does not move in the fourth slot 422, that is, at this time, the second hinge element 32, the first switching element 401 and the second switching element 402 remain relatively stationary at the same time, when the user applies force to the door 20 to drive the door 20 to open, the first switching element 401, the fourth switching element 322, and the fourth switching element 322 are located at the initial position D3925, The second switch member 402 and the second hinge member 32 are relatively stationary and move together relative to the first hinge member 31.

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 opposite direction.

It should be noted that, when the door 20 is in the process of being opened from the closed state to the first opening angle α 1, the third shaft 321 is always located at the starting position C1, and the fourth shaft 322 is always located at the rotation starting position D1, that is, the switching assembly 40 limits the second hinge element 32.

Here, when the door body 20 is in the closed state, the protrusion 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 first switch part 401, the second switch part 402, and the second hinge part 32 to move together relative to the first hinge part 31, the protrusion 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 switch part 401 cannot rotate relative to the first hinge part 31 any more, that is, the switch component 40 achieves 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, etc. of the protrusion 314 and the recessed portion 4016.

Meanwhile, in the opening process, the third engaging portion 405 is separated from the first engaging portion 315, and the third engaging portion 405 and the second engaging portion 316 gradually approach until the third engaging portion 405 is limited to the second engaging portion 316, specifically, the bottom surface of the first hinge member 31 abuts against the third boss 4051 to drive the third elastic member 4052 to compress, and when the third boss 4051 contacts the second engaging portion 316, the third elastic member 4052 resets to drive the third boss 4051 to enter the second engaging portion 316, which can further limit the first switching member 401 from continuing to rotate relative to the first hinge member 31.

It can be seen that, when the door body 20 is opened to the first opening angle α 1, the third boss 4051 and the second engaging portion 316 are limited by each other, and meanwhile, the first limiting surface 3141 and the second limiting surface 4017 are limited by each other, so that the first switching element 401 is prevented from continuously rotating relative to the first hinge element 31 by double limitation.

In addition, during the opening process, the sixth engaging portion 404 and the fourth engaging portion 4031 are always kept in a mutually restricted position to assist in the relative rest of the first switching member 401 and the second switching member 42.

Referring to fig. 24 to 28, 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 switch 401 and the first hinge 31 are relatively stationary, the second switch 402 and the second hinge 32 are relatively stationary and move together relative to the first switch 401, the door 20 moves away from the box 10 along the first direction X, and simultaneously, the center of gravity of the door moves toward the box 10.

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 fourth shaft 322 is maintained at the rotation starting position D1, the first shaft 311 moves from the first end B1 to the second end B2, the third shaft 321 moves from the starting position a1 to the stopping position a2, the third shaft 321 moves from the starting position C1 to the pivot position C2, and the fifth shaft 50 moves from the third end E1 to the fourth end E2, so that the door 20 can move away from the box 10 in the first direction X, and the center of gravity of the door moves toward the box 10.

Specifically, when the door 20 is opened to the first opening angle α 1, the first stopper surface 3141 abuts against the second stopper surface 4017 to make the first switching element 401 no longer move relative to the first hinge element 31, and/or the third engaging portion 405 and the second engaging portion 316 are mutually limited to make the first switching element 401 no longer move relative to the first hinge element 31, that is, the first hinge element 31 and the first switching element 401 are relatively stationary, and at this time, when the user continues to open the door 20 to make the door 20 in the process of continuing to open from the first opening angle α 1 to the second opening angle α 2, since the fourth slot body 422 is an arc slot with the pivot position C2 of the third slot body 421 as the center, before the third shaft body 321 moves to the pivot position C2, the fourth shaft body 322 does not move in the fourth slot body 422, that is, the second hinge element 402 and the second hinge element 32 are relatively stationary, at this time, the force of the user drives the first whole body formed by the second switching element 402 and the second hinge element 32 to relatively stationary The first switching member 401 and the first hinge member 31 form a second integral motion, that is, the second switching member 402 moves relative to the first switching member 401.

Here, the through hole 4026, the first lower slot 414 and the fifth slot 417 located at the second switching member 402 are all oval and parallel to each other, when the door 20 is in the process of opening from the first opening angle α 1 to the second opening angle α 2, the second switching member 402 moves relative to the first switching member 401, the first shaft 311 moves from the first end B1 to the second end B2 of the first lower slot 414, the third shaft 321 moves from the initial position a1 of the through hole 4026 to the stop position a2, the third shaft 321 also moves from the initial position C1 to the pivot position C2 of the third slot 421, the fifth shaft 50 moves from the third end E1 of the fifth slot 417 to the fourth end E2, at this time, the second switching member 402 moves a distance from the first switching member 401, and the second switching member 402 and the second hinge member 32 both move a distance from the door 20 to the door 10, at this time, and the door 20 is stationary, specifically, the door 20 moves away from the box 10 along the first direction X, and the center of gravity of the door moves toward the box 10, so that the opening degree can be increased, and the door can be prevented from falling.

It should be emphasized that the through hole 4026, the first lower slot 414 and the fifth slot 417 in this embodiment are all oval and parallel to each other, and when the door 20 is in the process of opening from the first opening angle α 1 to the second opening angle α 2, the second switch 402 substantially translates relative to the first switch 401 to drive the door 20 to translate relative to the box 10, but in other embodiments, the through hole 4026, the first lower slot 414 and the fifth slot 417 may also take other forms, for example, the through hole 4026, the first lower slot 414 and the fifth slot 417 take an arc shape, and the second switch 402 rotates relative to the first switch 401 to drive the door 20 to rotate relative to the box 10, and during the rotation, the door 20 moves away from the box 10 along the first direction X, and at the same time, the center of gravity of the door moves toward the box 10.

In addition, 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 fifth engaging portion 4032 and the sixth engaging portion 404 gradually approach to each other until the sixth engaging portion 404 is limited to the fifth engaging portion 4032, so that the relative movement between the first switch 401 and the second switch 402 is limited.

Specifically, in the opening process, the second switch piece 402 moves relative to the first switch piece 401 to drive the sixth engaging portion 404 to disengage from the fourth engaging portion 4031, and then the bottom surface of the first switch piece 401 close to the second switch piece 402 abuts against the sixth boss 4041 to drive the sixth elastic piece 4041 to compress, and when the sixth boss 4041 contacts the fifth engaging portion 4032, the sixth elastic piece 4041 resets to drive the sixth boss 4041 to enter the fifth engaging portion 4032.

Referring to fig. 29 to 33, 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, the first hinge member 31, the first switching member 401 and the second switching member 402 are relatively stationary, the second hinge member 32 moves relative to the second switching member 402, the third shaft body 321 is maintained at the stop position a2 and the pivot position C2, the fourth shaft body 322 moves from the rotation start position D1 to the rotation stop position D2, and the door 20 continues to rotate in place relative to the box 10.

Here, 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, the first shaft 311 is held at the second end B2 of the first lower slot 414, the third shaft 321 is held at the stop position a2 and the pivot position C2, the fifth shaft 50 is held at the fourth end E2 of the fifth slot 417, and the fourth shaft 322 moves from the rotation start position D1 to the rotation stop position D2, so that the door 20 can continuously rotate in place relative to the box 10.

Specifically, when the door 20 is opened to the second opening angle α 2, the first switching element 401 and the second switching element 402 are relatively stationary, and the first switching element 401 and the first hinge element 31 are relatively stationary, at this time, when the user continues to open the door 20, only the second hinge element 32 moves relative to the second switching element 402, and at this time, the third shaft 321 is located at the pivot position C2, the fourth shaft 322 is located at the rotation start position D1 of the fourth slot body 422, the fourth slot body 422 is an arc slot whose center is the pivot position C2 of the third slot body 421, when the user continues to open the door 20, the third shaft 321 is kept at the pivot position C2, and the fourth shaft 322 moves from the rotation start position D1 of the fourth slot body 422 to the rotation stop position D2, and during this opening process, the door 20 continues to rotate in place relative to the box 10.

It can be seen that the present embodiment can effectively control the sequential switching of the first hinge member 31 and the second hinge member 32, so that the door 20 can be stably opened, and the refrigerator 100 can adapt to an embedded application scenario.

It can be understood that the closing process of the door 20 is the reverse operation of the opening process of the door 20.

It should be noted that when the door body 20 is opened to the maximum opening angle α 3, the first switch piece 401 and the second switch piece 402 are limited by the sixth engaging portion 404 and the fifth engaging portion 4032, the acting force required by the sixth engaging portion 404 to disengage from the fifth engaging portion 4032 is the first acting force, the first switch piece 401 and the first hinge piece 31 are limited by the third engaging portion 405 and the second engaging portion 316, and the acting force required by the third engaging portion 405 to disengage from the second engaging portion 316 is the second acting force, in actual operation, the magnitudes of the first acting force and the second acting force can be controlled by structural settings, preferably, the first acting force is smaller than the second acting force, so that the door body 20 can firstly reset the second switch piece 402 and the first switch piece 401 during the closing process, and then reset the first switch piece 401 and the first hinge piece 31, of course, in other embodiments, the reset sequence during closing may be controlled in other ways.

In the present embodiment, when the door 20 is at the first opening angle α 1, the initial position a1 of the through hole 4026 is closer to the outer side 13 of the box 10 than the stop position a2, in other words, there is a fourth distance between the center of the third shaft 321 and the side edge 23, and there is a sixth distance between the center of the third shaft 321 and the side wall 22, when the door 20 is in the process of opening from the first opening angle α 1 to the second opening angle α 2, both the fourth distance and the sixth distance are in an increasing trend, that is, when the door 20 is in the process of opening from the first opening angle α 1 to the second opening angle α 2, the second switching element 402 moves relative to the first switching element 401, and the third shaft 321 moves in the through hole 4026 and the third groove 421 to change the distance between the center of the third shaft 321 and the side edge 23 and the side wall 22, where the fourth distance and the sixth distance are changed by the door 20 moving away from the box 10 in the first direction X, the opening degree can be increased.

In addition, when the door 20 is at the first opening angle α 1, the initial position a1 of the through hole 4026 is closer to the front end surface 103 than the stop position a2, in other words, a fifth distance is formed between the center of the third shaft 321 and the front wall 21, and when the door 20 is in the process of opening from the first opening angle α 1 to the second opening angle α 2, the fifth distance is reduced, where the change of the fifth distance is represented by the movement of the door 20 toward the front end surface 103 in the second direction Y, so that the center of gravity of the door moves toward the direction of the box 10, thereby preventing the door from toppling.

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. 34, 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 a process of opening to the first opening angle α 1 in a closed state, the door 20 rotates around the first shaft 311, a first distance is provided between the first shaft 311 and the front end surface 103, and when the door 20 is in a process of continuing to open from the second opening angle α 2 to the maximum opening angle α 3, the door 20 rotates around the third shaft 321, a second distance is provided between the third shaft 321 and 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 trajectories 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 around the first shaft 311, and then switching around the third shaft 321 through 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 on the side away 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 axis of the conventional refrigerator is approximately at the position of the first shaft body 311 in fig 34, 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. 34, a shaded area indicates the door 20 in a closed state, when the door 20 is in an opening process, if the door 20 rotates around the first shaft 311 (i.e. the prior art), referring to the door 20 'shown by a dotted line in fig. 34, 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 corner 203 of the cabinet 200 interferes with the door 20 ', so as 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 move 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. 34, 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 of ensuring that the refrigerator 100 is freely inserted into the cabinet 200, the refrigerator 100 can be conveniently operated by a user, and 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 body 321, which is finally used as a rotation shaft, may be located at other positions, for example, when the door body 20 rotates around the third shaft body 321, the third shaft body 321 is closer to the front end 201 of the cabinet 200 than the first shaft body 311, and the third shaft body 321 is farther away from the inner wall 202 of the cabinet 200 than the first shaft body 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 structures located in different regions of the door body 20 may be different, the hinge assembly 30 is located between the upper side of the door body 20 and the cabinet 10, and the structures of the hinge assemblies in other regions may refer to the description of the hinge assembly 30, and will not be described herein again.

Although the present invention has been described in detail with reference to the preferred embodiments, for example, if the techniques in different embodiments can be used in a superposition manner to achieve the corresponding effects, the embodiments are also within the protection scope of the present invention. It should be understood by those skilled in the art that various modifications and equivalents may be made to the present invention without departing from the spirit and scope of the invention.
