[0002] Among existing refrigerator products, multi-door side-by-side refrigerators have a promising future, and there are various styles of multi-door side-by-side refrigerators on the market. These refrigerators generally have a flip beam assembly. The function of the flip beam assembly is to make the door and the cabinet fit more tightly when the side doors are closed, reducing heat exchange between the inside and outside of the cabinet and preventing cold loss.

[0003] However, due to the assembly error gaps between the door and the tilting beam assembly during installation, and the high installation accuracy requirements of the existing tilting beam assembly, the seal between the box and the door is prone to failure due to assembly errors, resulting in the existing tilting beam assembly not being able to completely seal the box and the door. Utility Model Content

[0004] This utility model provides a flip beam assembly and a refrigerator, which solves the problem in the prior art that the flip beam assembly cannot completely seal the cabinet and door due to assembly errors.

[0006] A reversible flip beam body, which is connected to the door body via at least one pivotal assembly;

[0007] A sealing element, which is connected to the pivot assembly at the bottom of the tilting beam body via a transmission assembly;

[0008] When the door is opened relative to the inner liner of the box, the flip beam body flips, and the sealing element retracts into the flip beam body through the transmission component; when the door is closed relative to the inner liner of the box, the sealing element extends out of the flip beam body under the action of gravity, and adaptively seals and fits the inner liner of the box.

[0010] The tilting beam body is provided with at least two bearings, all of which are wound with traction ropes. One end of the traction rope is connected to the pivot assembly at the bottom of the tilting beam body, and the other end of the traction rope is connected to the seal.

[0011] Furthermore, when the door is opened relative to the inner liner of the box, a first angle is formed between the flip beam body and the pivot assembly, and the traction rope is folded. The value of the first angle is in the range of 10°-20°.

[0012] When the door is closed relative to the inner liner of the box, a second angle is formed between the flip beam body and the pivot assembly, and the folded traction rope is released. The value of the second angle is in the range of 100°-110°.

[0013] Furthermore, the outer wall of the tilting beam body is wrapped with an insulation component, and the insulation component is provided with a clearance groove corresponding to the traction rope, the clearance groove being used for the traction rope to pass through.

[0014] Furthermore, the bottom of the tilting beam body is provided with a through hole that matches the sealing element, and the transmission assembly drives the sealing element to extend or retract into the through hole.

[0016] Furthermore, an elastic element is provided between at least one of the pivot components and the corresponding door body, and a protective sleeve is matched on the elastic element;

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] When the door of this invention is opened relative to the inner liner of the refrigerator, the flip beam body drives the sealing element to retract into the flip beam body through the transmission component. When the door is closed relative to the inner liner of the refrigerator, the sealing element will extend from the bottom of the flip beam body according to its own weight, so that the sealing element adaptively seals and fits the inner liner of the refrigerator. This automatically compensates for assembly error gaps to achieve a seal, thereby ignoring assembly errors of the door and flip beam assembly during installation, minimizing heat exchange between the inner liner of the refrigerator and the external environment, effectively reducing cold air leakage, reducing condensation on the flip beam assembly, and reducing the power consumption of the refrigerator with the flip beam assembly installed.

[0047] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0048] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0049] Among existing refrigerator products, multi-door side-by-side refrigerators have a promising future, and there are various styles of multi-door side-by-side refrigerators on the market. These refrigerators generally have a flip beam assembly. The function of the flip beam assembly is to make the door and the cabinet fit more tightly when the side doors are closed, reducing heat exchange between the inside and outside of the cabinet and preventing cold loss.

[0050] However, due to the assembly error gaps between the door and the tilting beam assembly during installation, and the high installation accuracy requirements of the existing tilting beam assembly, the seal between the box and the door is prone to failure due to assembly errors, resulting in the existing tilting beam assembly not being able to completely seal the box and the door when closed.

[0051] Therefore, in some embodiments, such as Figures 1-3 As shown, this utility model proposes a flip beam assembly that can improve the sealing performance between the box body and the door body when closed, which is disposed on the door body 10; the flip beam assembly includes:

[0052] A reversible flip beam body 20 is connected to the door body 10 via at least one pivot assembly 30;

[0053] The seal 40 is connected to the pivot assembly 30 at the bottom of the tilting beam body 20 via the transmission assembly 50;

[0054] When the door 10 is opened relative to the inner liner 80, the flip beam body 20 flips, and the sealing element 40 retracts into the flip beam body 20 through the transmission assembly 50; when the door 10 is closed relative to the inner liner 80, the sealing element 40 extends out of the flip beam body 20 under the action of gravity, and adaptively seals and fits the inner liner 80.

[0055] It should be noted that this embodiment uses three pivot components 30 as an example. These three pivot components 30 are respectively arranged at the upper, middle, and lower parts of the tilting beam body 20, so that the door 10 can better open and close according to the tilting beam assembly and the inner liner 80 of the box. Each pivot component 30 is correspondingly provided with a protective cover plate 207, which is used to cover and protect the corresponding pivot component 30. Furthermore, the pivot component 30 proposed in this embodiment is preferably a hinge or other similar rotating connection component, which is not limited here.

[0056] The inner liner 80 of the refrigerator can also be equipped with a guide structure (not shown, the same throughout the text), which is used to guide the flipping trajectory of the flipping beam body 20. The flipping beam assembly proposed in this embodiment is illustrated using a refrigerator as an example.

[0057] Thus, as Figure 4 As shown, when the door 10 is opened relative to the inner liner 80, the tilting beam body 20 will tilt according to the opening of the door 10. Simultaneously, the tilting beam body 20, through the transmission assembly 50, drives the sealing element 40 to retract into the tilting beam body 20 (equivalent to the sealing element 40 performing an upward movement), so that the tilting beam assembly is in a closed state. Figure 5As shown, when the door 10 is closed relative to the inner liner 80, the flip beam body 20 will also flip according to the closing of the door 10. However, at this time, the transmission component 50 will not drive the seal 40 to extend. Instead, the seal 40 will extend from the bottom of the flip beam body 20 according to its own gravity (equivalent to the seal 40 making a downward movement) so that the flip beam assembly is in the unfolded state. This allows the seal 40 to adaptively seal and fit the inner liner 80, thereby automatically compensating for assembly error gaps to achieve sealing. This ignores the assembly error of the door 10 and the flip beam assembly during installation, thereby minimizing the heat exchange between the inner liner 80 and the external environment without increasing energy consumption, reducing the leakage of cold air, reducing the condensation of the flip beam assembly, reducing the power consumption of the refrigerator with the flip beam assembly, and saving money.

[0058] Furthermore, the seal 40 does not rub against the housing during the contraction or extension process, thereby reducing the resistance during the movement of the seal 40, reducing the wear of the seal 40, and extending the service life of the seal 40.

[0059] It should be noted that the assembly error of the door body 10 and the tilting beam assembly proposed in this embodiment during installation is within 3mm. Of course, the assembly error of the door body 10 and the tilting beam assembly proposed in this embodiment during installation can also be selected as other values ​​according to the actual situation, and is not limited to within 3mm.

[0060] In some embodiments, such as Figures 3-5 As shown, this embodiment proposes a transmission component 50, which includes a traction rope 501 and a bearing 502.

[0061] At least two bearings 502 are provided on the tilting beam body 20. All bearings 502 are wound with traction ropes 501. One end of the traction rope 501 is connected to the pivot assembly 30 located at the bottom of the tilting beam body 20, and the other end of the traction rope 501 is connected to the seal 40.

[0062] It should be noted that this embodiment uses two bearings 502 as an example because the two bearings 502 ensure more stable and reliable traction action of the traction rope 501. Furthermore, the two bearings 502 are distributed along the axial direction of the tilting beam body 20, and the axial height of all bearings 502 will not exceed the lowermost pivot assembly 30 of the tilting beam body 20. The traction rope 501 proposed in this embodiment is preferably made of polyester fiber or polypropylene, which has good flexibility, is suitable for traction on complex paths, and is lightweight, reducing the burden on the tilting beam assembly.

[0063] In this way, when the door 10 is opened relative to the inner liner 80, the flip beam body 20 will flip accordingly. Then, the flip beam body 20 will fold part of the traction rope 501, causing the traction rope 501 to immediately retract the seal 40 into the flip beam body 20, so that the flip beam assembly is in a closed state. When the door 10 is closed relative to the inner liner 80, the flip beam body 20 will also flip accordingly. At this time, the flip beam body 20 will release the folded traction rope 501, reducing the constraint on the stroke of the traction rope 501. At this time, the seal 40 will extend from the bottom of the flip beam body 20 according to its own weight, so that the flip beam assembly is in an unfolded state. This allows the seal 40 to adaptively seal against the inner liner 80, thus blocking the cold air in the inner liner 80, reducing the leakage of cold air, reducing condensation on the flip beam assembly, and reducing the power consumption of the refrigerator equipped with the flip beam assembly.

[0064] When the door 10 just begins to close relative to the inner liner 80 of the box, that is, when the tilting beam assembly initially unfolds, the seal 40 remains stationary due to inertia and the bearing 502. Then, the subsequent unfolding process of the tilting beam assembly is relatively fast, and the seal 40 will adaptively descend and fit onto the inner liner 80 of the box under the action of gravity.

[0065] Of course, this embodiment also has a 3mm redundancy in the constraint of the stroke of the traction rope 501 to compensate for the assembly error of the door body 10 and the flip beam assembly during installation; of course, the constraint of the stroke of the traction rope 501 can be selected as other values ​​according to the actual situation, and is not limited to 3mm.

[0066] In some embodiments, when the door 10 is opened relative to the inner liner 80 of the box, a first angle is formed between the flip beam body 20 and the pivot assembly 30, and the traction rope 501 is folded. The value of the first angle is in the range of 10°-20°.

[0067] When the door 10 is closed relative to the inner liner 80 of the box, a second angle is formed between the flip beam body 20 and the pivot assembly 30, and the folded traction rope 501 is released. The value of the second angle is in the range of 100°-110°.

[0068] Thus, to ensure the stability of the door 10 when it is open relative to the inner liner 80, a first angle is formed between the flip beam body 20 and the pivot assembly 30 so that the flip beam body 20 and the door 10 remain parallel. Similarly, to ensure the stability of the door 10 when it is closed relative to the inner liner 80, a second angle is formed between the flip beam body 20 and the pivot assembly 30 so that the flip beam body 20 and the door 10 remain perpendicular, and the first angle and the second angle must differ by 90°.

[0069] In some embodiments, such as Figures 2-3 As shown, at least one of the pivot components 30 and the corresponding door body 10 are further provided with an elastic element 204, and a protective sleeve 205 is matched on the elastic element 204;

[0070] When the door 10 is opened relative to the inner liner 80 of the box, the elastic element 204 undergoes elastic deformation and stores energy; when the door 10 is closed relative to the inner liner 80 of the box, the elastic element 204 resets and releases energy.

[0071] It should be noted that in this embodiment, an elastic element 204 is provided corresponding to the pivot assembly 30 located at the bottom of the tilting beam body 20, and the elastic element 204 proposed in this embodiment is preferably a torsion spring or a helical tension spring. The protective sleeve 205 is used to protect the elastic element 204 and to limit its movement, preventing it from detaching.

[0072] In this way, when the door 10 is opened relative to the inner liner 80, the elastic element 204 undergoes elastic deformation and stores energy; when the door 10 is closed relative to the inner liner 80, the elastic element 204 resets and releases energy, driving the flip beam assembly to complete the closing action. Thus, the elastic deformation of the elastic element 204 maintains the stable position of the flip beam assembly during the opening and closing process, preventing the door 10 from being opened or closed accidentally. In addition, the elastic element 204 can also absorb impact energy at the closing end of the door 10, reducing component wear and noise.

[0073] Furthermore, this embodiment proposes that due to the presence of the elastic element 204, the opening and closing of the tilting beam body 20 itself has dynamic redundancy, and the addition of the elastic element 204 will not cause resistance to the opening and closing of the door body 10.

[0074] In some embodiments, such as Figure 3 and Figure 6 As shown, the outer wall of the flip beam body 20 is wrapped with a heat insulation component 201. The heat insulation component 201 is provided with a relief groove 202 corresponding to the traction rope 501. The relief groove 202 is used to pass through the traction rope 501.

[0075] It should be noted that the insulation component 201 is preferably made of polyurethane foam or aerogel composite material. A fixing cover plate 208 is also provided on the outer wall of the insulation component 201, which is used to tightly attach the insulation component 201 to the outer wall of the flip beam body 20.

[0076] In this way, the insulation component 201 can fill the gap between the door 10 and the box, effectively blocking the leakage of cold air and the intrusion of hot air, and improving the overall insulation performance; and the insulation component 201 can also enhance the structural stability of the flip beam body 20, preventing deformation caused by frequent opening and closing.

[0077] Furthermore, in this embodiment, only a clearance groove 202 needs to be provided on the insulation component 201 to accommodate the traction rope 501 so that the traction rope 501 can pass through it. This way, it does not occupy too much space of the insulation component 201 and has little impact on the insulation performance of the insulation component 201.

[0078] In some embodiments, such as Figure 7 As shown, the bottom of the flip beam body 20 is provided with a through hole 203 that is adapted to the sealing member 40, and the transmission component 50 drives the sealing member 40 to extend or retract into the through hole 203.

[0079] Specifically, this embodiment presents one structural composition of the seal 40:

[0080] It includes a base plate 401, with a fixing block 402 at the top center of the base plate 401, and the other end of the traction rope 501 passes through the fixing block 402 and is bound thereto. The bottom of the base plate 401 has multiple spaced sealing plates 403 along the Y-axis, and each sealing plate 403 extends along the X-axis. The multiple spaced sealing plates 403 improve the sealing performance of the sealing element 40. Correspondingly, the bottom of the tilting beam body 20 also has multiple through holes 203 spaced along the Y-axis, and each through hole 203 extends along the X-axis. The axial direction of the tilting beam body 20 corresponds to the Z-axis direction, and so on.

[0081] It should be noted that the sealing plate 403 proposed in this embodiment adopts a composite structure of silicone rubber and rubber or a composite structure of silicone rubber and polyurethane, which takes into account elasticity, low temperature resistance (-30℃) and fatigue resistance. Its elastic properties can adapt to the slight deformation of the box surface and achieve adaptive fitting.

[0082] In this way, when the door 10 is opened relative to the inner liner 80 of the box, the traction rope 501 will drive the seal 40 to retract into the flip beam body 20 through the through hole 203, thereby hiding the seal 40.

[0083] Among them, such as Figures 8-9 As shown, the pivot assembly 30 located at the bottom of the tilting beam body 20 is provided with a rotating part 301. The rotating part 301 is located inside the corresponding tilting beam body 20 and can rotate inside the tilting beam body 20. The rotating part 301 is also provided with a fixing part 302. One end of the traction rope 501 passes through the corresponding tilting beam body 20 and is fixedly connected to the fixing part 302. When the door 10 is opened relative to the inner liner 80 of the box, the rotating part 301 will drive the fixing part 302 to rotate together, thereby folding part of the traction rope 501 and constraining the stroke of the traction rope 501. This allows the traction rope 501 to drive the sealing element 40 to retract immediately into the tilting beam body 20 through the through hole 203.

[0084] In some embodiments, to ensure that when the door 10 is closed relative to the inner liner 80 of the box, the impact vibration between the tilting beam body 20 and the door 10 is reduced, and the service life of the tilting beam assembly is extended, such as... Figure 2 As shown, at least one of the pivot components 30 is adapted to be provided with a vibration damping member 60; the vibration damping member 60 is used to reduce the impact vibration between the tilting beam body 20 and the door body 10.

[0085] It should be noted that this embodiment uses a vibration damping member 60 provided on the pivot assembly 30 located in the middle of the tilting beam body 20 as an example. Furthermore, the vibration damping member 60 proposed in this embodiment is preferably made of polyurethane or rubber.

[0086] In some embodiments, such as Figure 3 As shown, a buffer 206 is matched and provided on the top of the flip beam body 20.

[0087] In this way, when the door 10 closes relative to the inner liner 80, the buffer 206 will form a buffer contact with the contact surface on the door frame of the door 10, so as to absorb the impact energy when the door 10 closes through elastic deformation, effectively reducing collision noise; and the buffer 206 can also prevent the flip beam assembly from rigidly colliding with the door 10, extending the service life of the components; and when the door 10 closes relative to the inner liner 80, the buffer 206 can also undergo elastic deformation to enhance the sealing of the door 10, improve the heat preservation performance, and prevent cold loss.

[0088] In some embodiments, to prevent condensation from occurring on the flip beam assembly, such as Figure 3 As shown, a heating element 70 is provided axially inside the tilting beam body 20. The heating element 70 is used to heat the tilting beam body 20 to prevent condensation.

[0089] It is understood that the heating element 70 is electrically connected to the control unit inside the refrigerator. Furthermore, the tilting beam assembly is equipped with a detection device (not shown, same throughout) that is electrically connected to the control unit. The control unit receives real-time monitoring of parameters such as the temperature of the tilting beam assembly from the detection device. When the control unit detects that the surface temperature of the tilting beam assembly is lower than the ambient dew point temperature, it determines that condensation has occurred on the tilting beam assembly, at which point the control unit activates the heating element 70.

[0090] In some embodiments, such as Figure 1 As shown, this utility model also proposes a refrigerator, which includes the aforementioned flip beam assembly.

[0091] It should be noted that the refrigerator proposed in this embodiment is preferably a multi-door side-by-side refrigerator. The multi-door side-by-side refrigerator has at least one pair of side-by-side doors 10 and a corresponding inner liner 80. Each pair of side-by-side doors 10 is provided with a corresponding flip beam assembly so that the door 10 can be opened or closed relative to the inner liner 80 through the flip beam assembly.

[0092] In this way, when the door 10 is opened relative to the inner liner 80 of the box, the flip beam body 20 will flip according to the opening of the door 10, and at the same time as the flip beam body 20 flips, the transmission component 50 drives the seal 40 to retract into the flip beam body 20 (equivalent to the seal 40 making an upward movement), so that the flip beam assembly is in a closed state. When the door 10 closes relative to the inner liner 80, the flip beam body 20 also flips according to the closing of the door 10. However, at this time, the transmission component 50 does not drive the seal 40 to extend. Instead, the seal 40 extends from the bottom of the flip beam body 20 according to its own gravity (equivalent to the seal 40 making a downward movement) so that the flip beam assembly is in the unfolded state. This allows the seal 40 to adaptively seal and fit the inner liner 80, thereby automatically compensating for assembly error gaps to achieve a seal. This ignores the assembly error of the door 10 and the flip beam assembly during installation. Without increasing energy consumption, it minimizes the heat exchange between the inner liner 80 and the external environment, effectively reduces cold air leakage, reduces condensation on the flip beam assembly, reduces refrigerator power consumption, and saves money.

[0093] Furthermore, the seal 40 does not rub against the housing during the contraction or extension process, thereby reducing the resistance during the movement of the seal 40, reducing the wear of the seal 40, and extending the service life of the seal 40.

[0094] Furthermore, in this embodiment, the door 10 equipped with a flip beam assembly can be opened or closed independently relative to the inner liner 80, thereby improving the practicality of the refrigerator.

[0095] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
