Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigeration, in particular to a turnover beam assembly and a refrigerator. BACKGROUND

[0002] In the existing refrigerator products, the multi-door side-by-side refrigerator has a broad prospect, and there are various multi-door side-by-side refrigerators with different shapes on the market. These refrigerators generally have a turnover beam assembly. The turnover beam assembly can make the door body and the cabinet more closely fit when the side-by-side doors are closed, reduce the heat exchange between the inside of the cabinet and the outside environment, and prevent the loss of cold quantity.

[0003] However, due to the assembly error gap between the door body and the turnover beam assembly during installation, and the high installation precision requirement of the existing turnover beam assembly, the sealing between the cabinet and the door body is easily invalidated due to assembly error, so that the existing turnover beam assembly cannot completely seal the cabinet and the door body. SUMMARY

[0004] The present application provides a turnover beam assembly and a refrigerator, which solves the problem that the existing turnover beam assembly cannot completely seal the cabinet and the door body due to assembly error.

[0005] The technical scheme of the present application is a turnover beam assembly arranged on a door body. The turnover beam assembly comprises:

[0006] a turnover beam body which is connected to the door body through at least one pivot assembly;

[0007] a sealing member which is connected to the lowermost pivot assembly of the turnover beam body through a transmission assembly;

[0008] When the door body is opened relative to the cabinet liner, the turnover beam body is turned over, and the sealing member is retracted into the turnover beam body through the transmission assembly. When the door body is closed relative to the cabinet liner, the sealing member extends out of the turnover beam body under the action of gravity and self-adaptively seals and fits the cabinet liner.

[0009] Further, the transmission assembly comprises a traction rope and a bearing.

[0010] The turnover beam body is provided with at least two bearings, all of which are wound with a traction rope. One end of the traction rope is connected to the lowermost pivot assembly of the turnover beam body, and the other end of the traction rope is connected to the sealing member.

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

[0012] When the door body is closed relative to the inner container of the box body, a second included angle is formed between the turnover beam body and the pivot assembly, the folded traction rope is released, and the second included angle ranges from 100° to 110°.

[0013] Further, the outer side wall of the turnover beam body is wrapped with a heat preservation member, the heat preservation member is provided with a clearance groove corresponding to the traction rope.

[0014] Further, the bottom of the turnover beam body is provided with a through hole matched with the sealing member, and the transmission assembly drives the sealing member to extend out of or retract into the through hole.

[0015] Further, at least one of the pivot assemblies is provided with a damping member matched thereon; the damping member is used to reduce the impact vibration between the turnover beam body and the door body.

[0016] Further, an elastic member is further arranged between at least one of the pivot assemblies and the corresponding door body, and a protective sleeve is matched arranged on the elastic member.

[0017] When the door body is opened relative to the inner container of the box body, the elastic member is elastically deformed and stores energy; when the door body is closed relative to the inner container of the box body, the elastic member resets and releases energy.

[0018] Further, a buffer member is matched arranged on the top of the turnover beam body.

[0019] Further, a heating member is arranged in the turnover beam body along the axial direction, and the heating member is used to heat the turnover beam body to prevent condensation.

[0020] The application further provides a refrigerator comprising the turnover beam assembly.

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

[0022] When the door body is opened relative to the inner container of the box body, the turnover beam body drives the sealing member to retract into the turnover beam body through the transmission assembly, and when the door body is closed relative to the inner container of the box body, the sealing member extends out of the bottom of the turnover beam body according to its own gravity, so that the sealing member is self-adapted to seal and fit the inner container of the box body, thereby automatically compensating for the assembly error gap to realize sealing, thereby ignoring the assembly error of the door body and the turnover beam assembly during installation, maximally reducing the heat exchange between the inner container of the box body and the external environment, effectively reducing the cold air leakage amount, reducing the condensation of the turnover beam assembly, and reducing the power consumption of the refrigerator provided with the turnover beam assembly.

[0047] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clear and explicit, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application. Therefore, the features mentioned in the present specification are used to explain one of the features of one embodiment of the present application, and are not meant to imply that every embodiment of the present application must have the features explained. In addition, it should be noted that the present specification describes many features. Although some features can be combined together to show possible system designs, these features can also be used in other combinations that are not explicitly described. Therefore, unless otherwise specified, the described combinations are not intended to be limiting.

[0048] The principles and structures of the present application will be described in detail below in combination with the drawings and examples.

[0049] In existing refrigerator products, multi-door side-by-side refrigerators have broad prospects, and there are various multi-door side-by-side refrigerators with different shapes on the market. These refrigerators generally have a turnover beam assembly. The turnover beam assembly can make the door body and the cabinet fit more closely when the side-by-side doors are closed, reduce the heat exchange between the inside of the cabinet and the outside environment, and prevent the loss of cold quantity.

[0050] However, due to the assembly error gap between the door body and the turnover beam assembly during installation, and the high installation precision requirement of the existing turnover beam assembly, the sealing between the box body and the door body is easily affected by the assembly error, which leads to the fact that the existing turnover beam assembly cannot completely seal the box body and the door body when closed.

[0051] Therefore, in some embodiments, as Figures 1-3 shown, the present application proposes a turnover beam assembly capable of improving the sealing between the box body and the door body when closed, which is arranged on the door body 10; the turnover beam assembly comprises:

[0052] a turnover beam body 20 which is connected with the door body 10 through at least one pivot assembly 30;

[0053] a sealing member 40 which is connected with the lowermost pivot assembly 30 of the turnover beam body 20 through a transmission assembly 50;

[0054] Wherein, when the door body 10 is opened relative to the box inner container 80, the turnover beam body 20 is turned over, and the sealing member 40 is driven by the transmission assembly 50 to retract into the turnover beam body 20; when the door body 10 is closed relative to the box inner container 80, the sealing member 40 extends out of the turnover beam body 20 under the action of gravity, and self-adaptively seals and fits the box inner container 80.

[0055] It should be noted that the present embodiment takes three pivot assemblies 30 as an example, which are arranged at the upper, middle and lower parts of the turnover beam body 20, respectively, so that the door body 10 can better open and close according to the turnover beam assembly and the box inner container 80; and each pivot assembly 30 is correspondingly provided with a protective cover plate 207 for shielding and protecting the corresponding pivot assembly 30. The pivot assembly 30 proposed in the present embodiment is preferably a hinge or other similar rotary connecting assembly, which is not limited here.

[0056] Wherein, the box inner container 80 can also be correspondingly provided with a guide structure (not shown, same throughout the text), which is used to guide the turning trajectory of the turnover beam body 20. The turnover beam assembly proposed in the present embodiment is exemplified by being applied to a refrigerator.

[0057] In this way, as Figure 4 shown, when the door body 10 is opened relative to the box inner container 80, the turnover beam body 20 will turn over according to the opening of the door body 10, and at the same time, the turnover beam body 20 will drive the sealing member 40 to retract into the turnover beam body 20 through the transmission assembly 50 (equivalent to the upward movement of the sealing member 40), so that the turnover beam assembly is in a closed state. As Figure 5As shown, when the door body 10 is closed relative to the inner container 80 of the cabinet, the turnover beam body 20 will also be turned over according to the closing of the door body 10, but at this time the transmission assembly 50 will not drive the sealing element 40 to extend, but the sealing element 40 will extend from the bottom of the turnover beam body 20 according to its own gravity (equivalent to the sealing element 40 moving downward), so that the turnover beam assembly is in an unfolded state, so that the sealing element 40 is adaptively sealed and attached to the inner container 80 of the cabinet, thereby automatically compensating for the assembly error to achieve sealing, thereby ignoring the assembly error of the door body 10 and the turnover beam assembly during installation, thereby minimizing the heat exchange between the inner container 80 of the cabinet and the external environment without increasing energy consumption, reducing the leakage of cold air, reducing the condensation of the turnover beam assembly, reducing the power consumption of the refrigerator with the turnover beam assembly, and saving economy.

[0058] And the sealing element 40 does not rub with the cabinet during contraction or extension, thereby reducing the resistance during the movement of the sealing element 40 and reducing the wear of the sealing element 40, thereby prolonging the service life of the sealing element 40.

[0059] It should be noted that the assembly error of the door body 10 and the turnover beam assembly during installation according to the present embodiment is within 3mm, of course, the assembly error of the door body 10 and the turnover beam assembly during installation according to the present embodiment can also be selected as other values according to actual conditions, not limited to within 3mm.

[0060] In some embodiments, as shown, Figures 3-5 The present embodiment proposes a composition of the transmission assembly 50: including a traction rope 501 and a bearing 502;

[0061] The turnover beam body 20 is provided with at least two bearings 502, all the bearings 502 are wound with the traction rope 501, one end of the traction rope 501 is connected with the lowermost pivot assembly 30 of the turnover beam body 20, and the other end of the traction rope 501 is connected with the sealing element 40.

[0062] It should be noted that the present embodiment takes two bearings 502 as an example, because two bearings 502 ensure that the traction action of the traction rope 501 is more stable and reliable. And the two bearings 502 are distributed along the axial direction of the turnover beam body 20, and the axial height of all the bearings 502 will not exceed the lowermost pivot assembly 30 of the turnover beam body 20. And the material of the traction rope 501 according to the present embodiment is preferably polyester fiber or polypropylene, which has good flexibility, is suitable for complex path traction, and has light weight, which can reduce the burden of the turnover beam assembly.

[0063] Thus, when the door body 10 is opened relative to the inner container 80 of the cabinet, the turnover beam body 20 will be turned over according to the opening of the door body 10, and then the turnover beam body 20 will fold the part of the traction rope 501, so that the traction rope 501 drives the sealing element 40 to immediately retract into the turnover beam body 20, so that the turnover beam assembly is in a closed state. When the door body 10 is closed relative to the inner container 80 of the cabinet, the turnover beam body 20 will also be turned over according to the closing of the door body 10, at this time the turnover 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 sealing element 40 will extend from the bottom of the turnover beam body 20 according to its own gravity, so that the turnover beam assembly is in an unfolded state, so that the sealing element 40 is self-adapted to seal and fit the inner container 80 of the cabinet, so as to block the cold air in the inner container 80 of the cabinet, reduce the leakage of the cold air, and reduce the power consumption of the refrigerator installed with the turnover beam assembly.

[0064] At the beginning of the door body 10 closing relative to the inner container 80 of the cabinet, that is, the initial unfolding of the turnover beam assembly, at this time the sealing element 40 is not moved under the action of inertia and the bearing 502, and then the subsequent unfolding process of the turnover beam assembly is fast, and the subsequent sealing element 40 will be self-adapted to descend and fit to the inner container 80 of the cabinet under the action of gravity.

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

[0066] In some embodiments, when the door body 10 is opened relative to the inner container 80 of the cabinet, a first included angle is formed between the turnover beam body 20 and the pivot assembly 30, and the traction rope 501 is folded, and the value of the first included angle is 10°-20°;

[0067] When the door body 10 is closed relative to the inner container 80 of the cabinet, a second included angle is formed between the turnover beam body 20 and the pivot assembly 30, and the folded traction rope 501 is released, and the value of the second included angle is 100°-110°.

[0068] Thus, in order to ensure the stability of the door body 10 when it is opened relative to the inner container 80 of the cabinet, a first included angle is formed between the turnover beam body 20 and the pivot assembly 30, so that the turnover beam body 20 and the door body 10 remain in a parallel state; similarly, in order to ensure the stability of the door body 10 when it is closed relative to the inner container 80 of the cabinet, a second included angle is formed between the turnover beam body 20 and the pivot assembly 30, so that the turnover beam body 20 and the door body 10 remain in a perpendicular state, and the first included angle and the second included angle are different by 90°.

[0069] In some embodiments, as shown in Figures 2-3 An elastic member 204 is further arranged between the at least one pivot assembly 30 and the corresponding door body 10.

[0070] When the door body 10 is opened relative to the inner container 80 of the cabinet, the elastic member 204 is elastically deformed and stores energy; when the door body 10 is closed relative to the inner container 80 of the cabinet, the elastic member 204 resets and releases energy.

[0071] It should be noted that the elastic member 204 corresponding to the pivot assembly 30 located at the lowermost part of the turnover beam body 20 is arranged in this embodiment, and the elastic member 204 proposed in this embodiment is preferably a torsion spring or a spiral tension spring. The protective sleeve 205 is used to protect the elastic member 204 and limit the elastic member 204 to prevent it from coming off.

[0072] In this way, when the door body 10 is opened relative to the inner container 80 of the cabinet, the elastic member 204 is elastically deformed and stores energy; when the door body 10 is closed relative to the inner container 80 of the cabinet, the elastic member 204 resets and releases energy, driving the turnover beam assembly to complete the closing action, thereby maintaining the stable position of the turnover beam assembly during the opening and closing process through the elastic deformation of the elastic member 204, preventing the door body 10 from being accidentally opened or closed; and the elastic member 204 can also absorb impact energy at the end of the closing of the door body 10, reducing component wear and noise.

[0073] Moreover, due to the presence of the elastic member 204, the turnover beam body 20 has power redundancy for opening and closing, and the addition of the elastic member 204 does not cause resistance to the opening and closing of the door body 10.

[0074] In some embodiments, as shown in Figure 3 and Figure 6 The outer side wall of the turnover beam body 20 is wrapped with a heat preservation member 201, and the heat preservation member 201 is adapted to the traction rope 501 and is provided with a clearance groove 202 for passing through the traction rope 501.

[0075] It should be noted that the material of the heat preservation member 201 is preferably polyurethane foam or aerogel composite material. The outer side wall of the heat preservation member 201 is also provided with a fixed cover plate 208, which is used to tightly attach the heat preservation member 201 to the outer side wall of the turnover beam body 20.

[0076] In this way, the heat preservation member 201 can fill the gap between the door body 10 and the cabinet, effectively block the leakage of cold air and the invasion of hot air, and improve the overall heat preservation performance; and the heat preservation member 201 can also enhance the structural stability of the turnover beam body 20 to prevent deformation caused by frequent opening and closing.

[0077] And the embodiment only needs to be provided with a let go slot 202 corresponding to the traction rope 501 on the heat preservation part 201, so that the traction rope 501 passes through the slot, so as not to occupy too much space of the heat preservation part 201, and the influence on the heat preservation performance of the heat preservation part 201 is small.

[0078] In some embodiments, as shown in Figure 7 The bottom of the turnover beam body 20 is provided with a through hole 203 matched with the sealing piece 40, and the transmission assembly 50 drives the sealing piece 40 to extend out of or retract into the through hole 203.

[0079] Specifically, the embodiment proposes a structure of one of the sealing pieces 40:

[0080] It includes a base plate 401, a fixed block 402 is arranged at the top center of the base plate 401, and the other end of the traction rope 501 penetrates the fixed block 402 and is bound; a plurality of spaced sealing plates 403 are arranged on the bottom of the base plate 401 along the Y-axis direction, and each sealing plate 403 extends along the X-axis direction, and the plurality of spaced sealing plates 403 can improve the sealing performance of the sealing piece 40; of course, the bottom of the turnover beam body 20 is also provided with a plurality of through holes 203 spaced along the Y-axis direction corresponding to the sealing plates 403, and each through hole 203 extends along the X-axis direction. The axial direction of the turnover beam body 20 corresponds to the Z-axis direction, and the same applies throughout.

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

[0082] In this way, when the door body 10 is opened relative to the box inner container 80, the traction rope 501 drives the sealing piece 40 to pass through the through hole 203 to retract into the turnover beam body 20, thereby hiding the sealing piece 40.

[0083] As shown in Figures 8-9 The lowermost pivot assembly 30 of the turnover beam body 20 is provided with a rotating part 301, which is arranged in the corresponding turnover beam body 20, and the rotating part 301 can rotate in the turnover beam body 20; and the rotating part 301 is also provided with a fixed part 302, one end of the traction rope 501 penetrates the corresponding turnover beam body 20 and is fixedly connected with the fixed part 302, so that when the door body 10 is opened relative to the box inner container 80, the rotating part 301 drives the fixed part 302 to rotate together, thereby folding part of the traction rope 501, forming a constraint on the stroke of the traction rope 501, so that the traction rope 501 drives the sealing piece 40 to immediately retract into the turnover beam body 20 through the through hole 203.

[0084] In some embodiments, in order to reduce the impact vibration between the turnover beam body 20 and the door body 10 when the door body 10 is closed relative to the inner container 80 of the cabinet, prolong the service life of the turnover beam assembly, at least one of the pivot assemblies 30 is provided with a damping member 60, as shown in Figure 2 The damping member 60 is used to reduce the impact vibration between the turnover beam body 20 and the door body 10.

[0085] It should be noted that the damping member 60 is provided on the pivot assembly 30 in the middle of the turnover beam body 20 in the embodiment. The material of the damping member 60 is preferably polyurethane or rubber.

[0086] In some embodiments, as shown in Figure 3 The top of the turnover beam body 20 is provided with a buffer member 206.

[0087] In this way, when the door body 10 is closed relative to the inner container 80 of the cabinet, the buffer member 206 will form a buffer contact with the contact surface on the door frame of the door body 10, so as to absorb the impact energy when the door body 10 is closed through elastic deformation, effectively reducing the collision noise; and the buffer member 206 can also prevent rigid collision between the turnover beam assembly and the door body 10, prolonging the service life of the components; and when the door body 10 is closed relative to the inner container 80 of the cabinet, the buffer member 206 can also be elastically deformed to enhance the sealing performance of the door body 10, improve the heat preservation performance, and prevent the loss of cold energy.

[0088] In some embodiments, in order to avoid condensation of the turnover beam assembly, as shown in Figure 3 The turnover beam body 20 is provided with a heating member 70 in the axial direction, and the heating member 70 is used to heat the turnover beam body 20 to prevent condensation.

[0089] It can be understood that the heating member 70 is electrically connected to the control unit in the refrigerator. Correspondingly, a detection device (not shown, the same throughout the text) electrically connected to the control unit is provided on the turnover beam assembly, and the control unit receives the temperature and other parameters of the turnover beam assembly detected by the detection device in real time. When the control unit detects that the surface temperature of the turnover beam assembly is lower than the ambient dew point temperature, it is determined that the turnover beam assembly has condensation, and at this time the control unit starts the heating member 70.

[0090] In some embodiments, as shown in Figure 1 The present application also provides a refrigerator, which comprises the turnover beam assembly described above.

[0091] It should be noted that the refrigerator provided in the embodiment is preferably a multi-door side-by-side refrigerator, and the multi-door side-by-side refrigerator has at least one pair of door bodies 10 and corresponding inner tanks 80 of the cabinet in a side-by-side structure, and each door body 10 in each pair of the side-by-side structure is provided with a turnover beam assembly corresponding thereto, so that the door body 10 is opened or closed relative to the inner tank 80 of the cabinet through the turnover beam assembly.

[0092] In this way, when the door body 10 is opened relative to the inner tank 80 of the cabinet, the turnover beam body 20 will be turned over according to the opening of the door body 10, and the turnover beam body 20 will drive the sealing element 40 to retract into the turnover beam body 20 (equivalent to the upward movement of the sealing element 40) at the same time of turning over through the transmission assembly 50, so that the turnover beam assembly is in a closed state. When the door body 10 is closed relative to the inner tank 80 of the cabinet, the turnover beam body 20 will also be turned over according to the closing of the door body 10, but at this time the transmission assembly 50 will not drive the sealing element 40 to extend, but the sealing element 40 will extend from the bottom of the turnover beam body 20 according to its own gravity (equivalent to the downward movement of the sealing element 40), so that the turnover beam assembly is in an unfolded state, so that the sealing element 40 is self-adapted to seal and fit the inner tank 80 of the cabinet, thereby automatically compensating for the assembly error gap to realize sealing, thereby ignoring the assembly error of the door body 10 and the turnover beam assembly during installation, minimizing the heat exchange between the inner tank 80 of the cabinet and the external environment without increasing energy consumption, effectively reducing the amount of cold air leakage, reducing the condensation of the turnover beam assembly, reducing the power consumption of the refrigerator, and saving the economy.

[0093] And the sealing element 40 does not rub against the cabinet during retraction or extension, thereby reducing the resistance during the movement of the sealing element 40 and reducing the wear of the sealing element 40, thereby prolonging the service life of the sealing element 40.

[0094] And the door body 10 provided with the turnover beam assembly in the embodiment can be opened or closed relative to the inner tank 80 of the cabinet alone, thereby improving the practicability of the refrigerator.

[0095] Obviously, the above-described embodiments are only some of the embodiments of the present application, not all the embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any equivalent structure made by using the contents of the specification and drawings, directly or indirectly applied to other related technical fields, is also within the patent protection scope of the present application.
