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.
With reference to fig. 10 to 13, when the door 20 is in the closed state, the first switching member 401 and the second switching member 402 are relatively stationary, the first upper free section 4131 and the first lower free section 4141 are overlapped to form a first free section S1, the second upper free section 4151 and the second lower free section 4161 are overlapped to form a second free section S2, the first shaft 311 is located at the initial position A1, and the second shaft 312 is located at an end of the first section L1 away from the second section L2.
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.
Referring to fig. 14 to 17, when the door 20 is in the process of opening from the closed state to the first intermediate opening angle α 11, the first switching member 401 and the second switching member 402 are relatively stationary, the first upper free section 4131 and the first lower free section 4141 are overlapped to form a first free section S1, the second upper free section 4151 and the second lower free section 4161 are overlapped to form a second free section S2, the second shaft 312 moves in the first section L1 to drive the first shaft 311 to move from the initial position A1 to the stop position A2, and the door 20 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 surrounding cabinets or walls and the like 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.
Referring to fig. 18 to 21, when the door body 20 is in the process of continuously opening from the first intermediate opening angle α 11 to the first opening angle α 1, the first switching member 401 and the second switching member 402 are relatively stationary, the first upper free section 4131 and the first lower free section 4141 are overlapped to form a first free section S1, the second upper free section 4151 and the second lower free section 4161 are overlapped to form a second free section S2, the second shaft 312 moves in the second section L2 to drive the first shaft 311 to move from the stop position A2 toward the initial position A1, and the door body 20 moves from the accommodating chamber S toward the pivot side P to keep the side edge 23 on the side of the outer side 13 close to the accommodating chamber S.
Here, the lateral edges 23 move in the plane of the outer lateral surface 13 and gradually approach the receiving chamber S.
It can be understood that, when the door 20 is in the process of continuing to open from the second intermediate opening angle α 12 to the first opening angle α 1, if the door 20 rotates in situ relative to the box 10, the side edge 23 gradually moves toward a side close to the accommodating chamber S, and meanwhile, the door 20 gradually moves close to the accommodating chamber S, and the door 20 may obstruct the opening of the drawer, the rack, and the like in the box 10, that is, the opening degree of the box 10 may be reduced.
The hinge assembly 30 of the present embodiment drives the side edge 24 to move in the plane of the outer side surface 13, so that the door 20 is away from the box 10 as much as possible, the opening degree of the box 10 is ensured, the problem that drawers, racks and the like in the box 10 cannot be opened due to interference of the door 20 is avoided, and the side edge 23 is prevented from protruding out of the outer side surface 13 in the direction away from the accommodating chamber S.
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.
In addition, in the process, the first upper free segment 4131 and the first lower free segment 4141 are always recombined into the first free segment S1, and the second upper free segment 4151 and the second lower free segment 4161 are always recombined into the second free segment S2, that is, the movement trajectories of the first switching element 401 and the second switching element 402 are completely the same, and the first shaft element 311 moves in the first free segment S1, and the second shaft element 312 moves in the second free segment S2, so that the first switching element 401 and the second switching element 402 are not staggered with each other all the time in the process, that is, the first switching element 401 and the second switching element 402 are kept stationary relative to each other, so as to prevent the first upper free segment 4131 and the first lower free segment 4141 from being staggered with each other, and to prevent the second upper free segment 4151 and the second lower free segment 4161 from being staggered with each other, so as to ensure that the first shaft element 311 moves smoothly in the first free segment S1, and the second shaft element 312 moves smoothly in the second free segment S2.
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 position-limiting section 4222, and the first shaft 311 and/or the second shaft 312 are/is limited by the locking sections 4132, 4142, 4152, 4162 to limit the switching assembly 40 at the first hinge 31.
Here, "the first switching element 401 and the second switching element 402 move relatively to separate the second hinge element 32 from the position of the switching component 40, and the first shaft 311 and/or the second shaft 312 are limited by the locking segments 4132, 4142, 4152, 4162 to limit the switching component 40 on the first hinge element 31" means that there is no mutual limit between the switching component 40 and the second hinge element 32 due to the relative movement between the switching component 40 and the second hinge element 32, and there is no mutual limit between the switching component 40 and the second hinge element 32 due to the relative movement between the switching component 40 and the first hinge element 31 to limit the switching component 40 and the first hinge element 31.
In the present embodiment, the first shaft 311 is simultaneously constrained by the first upper locking section 4132 and the first lower locking section 4142, the second shaft 312 is simultaneously constrained by the second upper locking section 4152 and the second lower locking section 4162, and the fourth shaft 322 is disengaged from the fourth constraining section 4222, as follows:
when the door 20 is opened to the first opening angle α 1, the second shaft 312 moves from the second free section S2 to the second lower locking section 4162 for limiting, at this time, the first shaft 311 and the second shaft 312 cannot move relative to the first free section S1 and the second free section S2 any more, and at this time, the first shaft 311 is adjacent to the first upper locking section 4132 and the first lower locking section 4142, the second shaft 312 is adjacent to the second upper locking section 4152, and the track of the first upper locking section 4132 and the track of the second upper locking section 4152 adapt to the movement path of the first shaft 311 and the second shaft 312.
When the door 20 continues to be opened based on the first opening angle α 1, the door 20 drives the second hinge element 32 connected to the door 20 to move, the second hinge element 32 applies an acting force to the third shaft 321 and the fourth shaft 322 through the third free section 4211 and the fourth limiting section 4222, and the third shaft 321 and the fourth shaft 322 drive the first switching element 401 and the second switching element 402 to move.
Specifically, at this time, the first shaft 311 is adjacent to the first upper locking section 4132, the second shaft 312 is adjacent to the second upper locking section 4152, the first switching element 401 can move relative to the first shaft 311 and the second shaft 312 by a first angle until the first shaft 311 is limited by the first upper locking section 4132 and the second shaft 312 is limited by the second upper locking section 4152, and meanwhile, the second switching element 402 moves relative to the first shaft 311 by a second angle using the fifth shaft 50 as a center until the first shaft 311 is limited by the second upper locking section 4152, during this process, the second shaft 312 is always in contact with the second lower locking section 4162, and the second angle is greater than the first angle.
That is to say, the first switch 401 and the second switch 402 both rotate a certain angle, and the rotation angle of the second switch 402 is greater than that of the first switch 401, so that the first switch 401 and the second switch 402 also move relatively to each other.
It can be understood that the rotation processes of the first switching member 401 and the second switching member 402 are not in a certain sequence, and the first switching member 401 and the second switching member 402 may rotate simultaneously, for example, the first switching member 401 and the second switching member 402 rotate synchronously within a certain rotation angle range, and then the first switching member 401 and the second switching member 402 are staggered.
In practical operation, the first switch element 401 and the second switch element 402 drive the first slot 411 and the second slot 412 to rotate relative to the first shaft 311 and the second shaft 312, respectively, the first shaft 311 is separated from the first free section S1 and abuts against the first upper locking section 4132 and the first lower locking section 4142, that is, the first shaft 311 is simultaneously limited by the first upper locking section 4132 and the first lower locking section 4142, the second shaft 312 is separated from the second free section S2 and abuts against the second upper locking section 4152 and the second lower locking section 4162, that is, the second shaft 312 is simultaneously limited by the second upper locking section 4152 and the second lower locking section 4162, and meanwhile, the movement of the second switch element 402 causes the fourth shaft 322 to be separated from the fourth limiting section 4222.
It can be understood that when the first shaft 311 is located at the first upper locking section 4132 and the first lower locking section 4142, since the first switching member 401 and the second switching member 402 are staggered, the first upper free section 4131 and the first lower free section 4141, which are originally overlapped with each other, are also staggered with each other, and at this time, the staggered first upper free section 4131 and the first lower free section 4141 limit the first shaft 311 from being separated from the first upper locking section 4132 and the first lower locking section 4142, so that the first shaft 311 can be ensured to be always kept at the first upper locking section 4132 and the first lower locking section 4142 in the process of continuously opening the door 20.
Similarly, when the second shaft 312 is located at the second upper locking section 4152 and the second lower locking section 4162, since the first switching member 401 and the second switching member 402 are staggered, the second upper free section 4151 and the second lower free section 4161, which are originally overlapped with each other, are also staggered, and at this time, the staggered second upper free section 4151 and the second lower free section 4161 limit the second shaft 312 from being separated from the second upper locking section 4152 and the second lower locking section 4162, so that the second shaft 312 is always kept at the second upper locking section 4152 and the second lower locking section 4162 in the process of continuously opening the door 20.
In addition, the rotation angle of the second switching member 402 is greater than that of the first switching member 401, that is, the second switching member 402 and the first switching member 401 are staggered from each other, so that the locking effect between the first hinge member 31 and the switching assembly 40 can be further improved, and it is ensured that the first shaft body 311 is always kept at the first upper locking section 4132 and the first lower locking section 4142, and the second shaft body 312 is always kept at the second upper locking section 4152 and the second lower locking section 4162.
In the present embodiment, the first upper locking section 4132 is a portion of the first upper free section 4131 close to the initial position A1, when the door 20 is opened to the first opening angle α 1, the first shaft 311 moves from the stop position A2 toward the initial position A1 without reaching the initial position A1, and 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, the first shaft 311 moves to the initial position A1 (i.e., moves to the first upper locking section 4132), and simultaneously, the second shaft 312 moves to the first lower locking section 4142, and in this process, the door 20 substantially continues to move from the accommodating chamber S toward the pivoting side P.
Referring to fig. 26 to 29, when the door body 20 is in the process of opening from the second opening angle α 2 to the maximum opening angle α 3, the first switching member 401 and the second switching member 402 are relatively stationary, the third shaft body 321 moves in the third free segment 421, and the fourth shaft body 322 moves in the fourth free segment 4221.
Here, the first opening angle α 1 is approximately 80 ° to 83 °, the second opening angle α 2 is approximately 90 °, and the maximum opening angle α 3 is greater than 90 °, that is, in a process of opening the door 20 to 80 ° to 83 °, the door 20 is first displaced along the first direction X to prevent the door 20 from interfering with a peripheral cabinet or wall during the opening process, and then the door 20 is displaced along the second direction Y to prevent the door 20 from obstructing the opening of a drawer, a rack, and the like in the box 10, and finally reaches 80 ° to 83 °, and thereafter, in a process of continuing to open the door 20 to 90 °, the switching assembly 40 is moved to enable the door 20 to continue to rotate with the rotating shaft replaced, that is, after 90 °, the door 20 continues to rotate in situ relative to the box 10 with the third shaft 321 as the rotating shaft to further open the door 20.
It is to be understood that the angles are not limited by the above description.
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.
It can be understood that when the door 20 is in a closing process, that is, when the door 20 starts to close from the maximum opening angle α 3, the switching component 40 can also effectively control the sequential switching of the first hinge component 31 and the second hinge component 32, that is, when the door 20 is in a process of closing from the maximum opening angle α 3 to the second opening angle α 2, the third shaft component 321 moves in the third free segment 4211, the fourth shaft component 322 moves in the fourth free segment 4221, and the switching component 40 locks the first hinge component 31, when the door 20 is in a process of closing from the second opening angle α 2 to the first opening angle α 1, the first switching component 401 and the second switching component 402 relatively move to make the first hinge component 31 disengage from the limit of the switching component 40, and the fourth shaft component 322 is limited in the fourth limit segment 4222, the switching component 40 locks the second hinge component 32, and when the door 20 is in a process of closing from the first opening angle α 1 to the complete closing process, the first free segment S1 moves, and the first shaft component 311 moves in the second free segment S312 moves in the second free segment S2.
In other words, the closing process of the door body 20 and the opening process of the door body 20 are processes in reverse order, and the switching sequence of the first hinge part 31 and the second hinge part 32 in the opening and closing processes of the door body 20 can be effectively controlled through the unlocking and locking effects of the switching assembly 40 on the first hinge part 31 and the second hinge part 32.
In the present embodiment, a first distance is formed between the center of the first shaft 311 and the side edge 23, a second distance is formed between the center of the first shaft 311 and the front wall 21, a third distance is formed between the center of the first shaft 311 and the side wall 22, 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, when the door 20 is opened from the closed state to the first opening angle α 1, the first distance, the second distance, and the third distance all tend to decrease and then increase, 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 remain unchanged.
In addition, in the present embodiment, the first shaft 311 and the third shaft 321 are offset from each other, and thus, the present invention is applicable to a built-in cabinet or a scene where a space for accommodating the refrigerator 100 is small.
Referring to fig. 30, a simple schematic view 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 a receiving 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 away from the receiving chamber S and a side wall 22 interposed between the front wall 21 and the receiving chamber S, and a side edge 23 is disposed 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 tracks of the refrigerator 100, the first shaft 311 and the third shaft 321 move relative to the door 20, or the hinge assembly 30 further includes a second shaft 312 engaged with the first shaft 311 and a fourth shaft 322 engaged with the third shaft 321, for simplicity of description, it is simply regarded that the door 20 rotates with the first shaft 311 as a shaft first, and then is switched to rotate with the third shaft 321 as a shaft through the switching assembly 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 maintained between a rotating shaft of the refrigerator and a side wall and a front wall of the refrigerator, so that there is enough space to satisfy foaming or other processes, that is, the rotating shaft of the existing refrigerator is approximately located at a position of a first shaft body 311 in fig. 30, in this case, after the single-shaft refrigerator is embedded into a cabinet 200, since an edge 203 of the cabinet 200, which is sandwiched between a front end 201 and an inner wall 202, is arranged corresponding to a side edge 23 of a door body 20, when the door body 20 is opened, the side edge 23 interferes with the door body 20 to limit a maximum opening angle of the door body 20, and in order to ensure normal opening of the door body 20, a common method in the prior art is to increase a gap between the inner wall 202 of the cabinet 200 and the refrigerator 100, which needs to be approximately 10cm or so, and this will seriously affect an embedding effect, and is not favorable for reasonable utilization of the limited space.
Referring to fig. 30, 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. in the prior art), referring to the door 20 'shown by a dotted line in fig. 30, 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 '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, at this time, the whole door 20 moves toward the direction away from the box 10, referring to the solid-line door 20 in fig. 30, 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.
Moreover, 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, and the refrigerator 100 and the cabinet 200 can be seamlessly connected, thereby greatly improving the insertion effect.
In addition, the switching component 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 around 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 to make the door 20 away from the box 10 to increase the opening degree of the box 10, thereby facilitating the opening and closing of the racks, drawers, etc. in the box 10, or facilitating the taking and placing of the 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 part 31 and the second hinge part 32 in the opening and closing processes of the door body 20, so that the door body 20 can be effectively prevented from interfering with the cabinet 200 in the opening and closing processes.
In addition, it should be noted that the motion trajectory of the door 20 can be effectively controlled through a specific design of the shaft slot, in this embodiment, the box 10 includes a pivoting side P connected to the hinge assembly 30, and when the door 20 is in the opening process, the hinge assembly 30 at least drives the door 20 to move from the pivoting side P toward the accommodating chamber S, so as to avoid the door 20 from interfering with a peripheral cabinet or wall in the opening process, and the following embodiment can be referred to for the specific design of the shaft slot.
In the present embodiment, the hinge assembly 30 is configured to be located at different regions of the door body 20, the hinge assembly 30 is a hinge assembly 30 located between the upper side of the door body 20 and the container body 10, and hereinafter, the hinge assembly 30' located between the lower side of the door body 20 and the container body 10 will be briefly described with reference to fig. 31 and 32.
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', and 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 open 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' along 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'.
