Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator beam structure and a refrigerator. Background Technology

[0002] In existing refrigerators, hinges are usually fixed at the left and / or right ends of the center beam so that the door can be rotatably connected to the refrigerator body via the hinge axis on the hinge.

[0003] In current technology, the central beam is prone to deformation or displacement during transportation or long-term storage, resulting in misalignment between the door and the loading / unloading openings of the box. Utility Model Content

[0004] The main purpose of this invention is to propose a refrigerator central beam structure that aims to reduce the probability of deformation and displacement of the central beam.

[0005] To achieve the above objectives, the refrigerator center beam structure proposed in this utility model includes: A central beam, wherein the central beam is provided with a mounting groove extending along the length direction of the central beam; and Multiple reinforcing members are spaced apart along the length of the mounting groove. Each reinforcing member has two reinforcing walls that abut against the side wall of the mounting groove. The side of each reinforcing wall away from the central beam is provided with multiple sequentially bent limiting flanges, forming a limiting groove on the reinforcing member.

[0006] In one embodiment, the width of the limiting groove is increased in the direction away from the middle beam.

[0007] In one embodiment, the multiple limiting flanges include a first flange and a second flange. The first flange is located on the side of the reinforcing wall away from the middle beam and extends outward from the mounting groove. The second flange is located on the side of the first flange away from the reinforcing wall and extends in a direction away from the middle beam.

[0008] In one embodiment, the spacing between the two reinforcing walls ranges from 12 mm to 16 mm; and / or The spacing between the two second flanges ranges from 22mm to 28mm.

[0009] In one embodiment, the multiple limiting flanges further include a third flange, which is located on the side of the second flange away from the first flange.

[0010] In one embodiment, the reinforcing member further has a connecting wall that connects two reinforcing walls. The connecting wall has a first fastening hole, and the central beam has a second fastening hole corresponding to the first fastening hole. Fasteners pass through the first fastening hole and the second fastening hole in sequence to fasten the reinforcing member and the central beam together.

[0011] In one embodiment, the connecting wall is riveted to the central beam.

[0012] In one embodiment, at least one reinforcing member is provided at each end of the mounting groove, and the reinforcing member at the end of the mounting groove is provided with an extension section extending outward from the mounting groove, and each side of the extension section has at least one reinforcing portion extending laterally towards the mounting groove.

[0013] In one embodiment, the width of the mounting groove ranges from 15 mm to 19 mm.

[0014] This utility model also proposes a refrigerator, including the aforementioned refrigerator beam structure.

[0015] The technical solution of this utility model involves setting a reinforcing member in the mounting groove and providing multiple sequentially bent limiting flanges on the side of the two reinforcing walls away from the central beam. It can be understood that after the refrigerator is installed, the reinforcing member is surrounded by foam material to form a foam layer. That is, the foam material of the cabinet will expand and flow into the limiting groove of the reinforcing member, causing the sequentially bent limiting flanges and the surrounding foam layer to cooperate and limit each other from multiple directions, forming a mechanical interlocking structure. This greatly enhances the bonding force between the reinforcing member and the cabinet, thereby reducing the probability of deformation or displacement of the reinforcing member, which in turn reduces the probability of deformation or displacement of the central beam, and further reduces the probability of displacement of the door installed on the central beam. This greatly solves the problem of misalignment between the door and the refrigerator cabinet opening caused by door displacement. Attached Figure Description

[0023] In existing refrigerators, hinges are usually fixed at the left and / or right ends of the center beam so that the door can be rotatably connected to the refrigerator body via the hinge axis on the hinge.

[0024] In current technology, the central beam is prone to denting during transportation or long-term storage, resulting in misalignment between the door and the opening for taking out and putting in the box.

[0025] This utility model proposes a central beam structure for a refrigerator.

[0026] Please see Figures 1 to 3 In one embodiment of this utility model, the refrigerator's central beam structure includes a central beam 100 and a plurality of reinforcing members 200. The central beam 100 is provided with a mounting groove 110, which extends along the length direction of the central beam 100. The plurality of reinforcing members 200 are spaced apart along the length direction of the mounting groove 110. Each reinforcing member 200 has two reinforcing walls 210 that abut against the side wall of the mounting groove 110. The two reinforcing walls 210 are provided with multiple successively bent limiting flanges 220 on the side away from the central beam 100, and limiting grooves 230 are formed on the reinforcing members 200.

[0027] The technical solution of this utility model is to set a reinforcing member 200 in the mounting groove 110, and to provide multiple successively bent limiting flanges 220 on the side of the two reinforcing walls 210 away from the central beam 100. It can be understood that after the refrigerator is installed, the reinforcing member 200 is surrounded by foam material to form a foam layer. That is, the foam material of the cabinet will expand and flow into the limiting groove 230 of the reinforcing member 200, so that the multiple successively bent limiting flanges 220 and the surrounding foam layer cooperate with each other from multiple directions to limit and form a mechanical interlocking structure. This greatly enhances the bonding force between the reinforcing member 200 and the cabinet, thereby reducing the probability of deformation or displacement of the reinforcing member 200, reducing the probability of deformation or displacement of the central beam 100, and further reducing the probability of displacement of the door installed on the central beam 100. This greatly solves the problem of misalignment between the door and the refrigerator cabinet opening caused by door displacement.

[0028] Secondly, this solution solves the problem of misalignment between the door and the refrigerator compartment opening caused by door displacement by setting multiple sequentially bent limiting flanges 220 in the reinforcing wall 210. This method has a simple structure and simple manufacturing process, which helps to reduce the production cost of the refrigerator's central beam structure. In other words, this solution solves the problem of misalignment between the door and the refrigerator compartment opening caused by door displacement in a low-cost way.

[0029] Reference Figure 5In this embodiment, the central beam 100 is also provided with a first slot and a second slot. The first slot and the second slot are respectively located on opposite sides of the mounting groove 110, and the openings of the first slot and the second slot are located on the side of the central beam 100. One of the first slot and the second slot is used to accommodate part of the inner liner of the refrigerator, and the other is used to accommodate part of the inner liner of the freezer.

[0030] In one embodiment, the center beam 100 includes a flat center beam 100 body and two curved sections. The two curved sections are connected to both sides of the center beam 100 body and bend towards the center of the center beam 100 body. Each curved section partially fits into the center beam 100 body, forming a cavity on both sides of the center beam 100 body. After fitting into the center beam 100 body, the curved section bends away from the center beam 100 body to form a mounting groove 110. The opening of the mounting groove 110 bends outwards towards the center beam 100 body to form a first retaining groove and a second retaining groove, respectively. The cavity design improves the bending strength of the center beam 100, preventing it from sagging during foaming. This results in better adhesion between the center beam 100 and the door seal, improving the sealing effect between the center beam 100 and the door seal, preventing cold air leakage, and thus improving the quality of the refrigerator. Here, the center of the center beam 100 body refers to the center of the center beam 100 in the width direction.

[0031] Reference Figure 4 and Figure 5 Optionally, the width of the limiting groove 230 increases in the direction away from the center beam 100. This improves the gripping ability of the reinforcing member 200 on the foam layer, thereby increasing the reliability of the gripping of the center beam 100 and reducing the probability of deformation or displacement of the reinforcing member 200. This, in turn, reduces the likelihood of deformation or displacement of the center beam 100, and consequently, reduces the probability of displacement of the door body installed on the center beam 100. Of course, this solution is not limited to this. In other embodiments, the width of the limiting groove 230 can be initially increased, then decreased, and then increased again in the direction away from the center beam 100.

[0032] Furthermore, the multiple limiting flanges 220 include a first flange 221 and a second flange 222. The first flange 221 is located on the side of the reinforcing wall 210 away from the middle beam 100 and extends outward from the mounting groove 110. The second flange 222 is located on the side of the first flange 221 away from the reinforcing wall 210 and extends in a direction away from the middle beam 100. This can further improve the gripping ability of the reinforcing member 200 on the foam layer, thereby improving the reliability of the gripping of the middle beam 100, and thus reducing the probability of deformation or displacement of the reinforcing member 200, thereby reducing the probability of deformation or displacement of the middle beam 100, and further reducing the probability of displacement of the door body installed on the middle beam 100, and reducing the probability of misalignment between the door body and the opening of the box.

[0033] In one embodiment, the width of the mounting groove 110 ranges from 15mm to 19mm, that is, the width of the mounting groove 110 is denoted as X1, 15mm≤X1≤19mm. It can be understood that by increasing the width of the mounting groove 110, not only can the width of the mounting groove 110 be expanded, but also sufficient space is provided for the reinforcing member 200, so that the cross-section of the reinforcing member 200 can be made large enough, thereby improving the gripping ability of the middle beam 100 and the reinforcing member 200 on the foam layer, improving the gripping reliability of the middle beam 100, and thus effectively resisting the bending and torsional stress generated during the opening and closing of the door, the placement of items, and the handling process, thereby reducing the probability of displacement of the door installed on the middle beam 100 and reducing the probability of misalignment between the door and the opening of the box.

[0034] In this embodiment, the width of the mounting groove 110 is 17mm. This allows for an increase in the width of the mounting groove 110 without affecting the volume of the first and second slots, thereby further improving the gripping ability of the center beam 100 and the reinforcing member 200 on the foam layer, enhancing the reliability of the center beam 100's gripping, and consequently reducing the probability of door displacement on the center beam 100 and the probability of misalignment between the door and the housing's openings. In other embodiments, the width of the mounting groove 110 can also be 16mm, 17.5mm, 18mm, or 15mm.

[0035] In this embodiment, the distance between the two reinforcing walls 210 is 12mm to 16mm; and / or the distance between the two second flanges 222 is 22mm to 28mm; it can be understood that the limiting groove 230 has a first groove and a second groove that are connected, the first groove is formed between the two reinforcing walls 210, and the second groove is formed between the two second flanges 222.

[0036] The spacing between the two reinforcing walls 210 ranges from 12mm to 16mm, denoted as X2, where 12mm ≤ X2 ≤ 16mm. The 12mm to 16mm wide limiting groove 230 provides a clear flow channel and filling space for the foaming material. This improves the adhesion of the reinforcing member 200 to the foam layer, effectively resisting bending and torsional stresses generated during door opening and closing, item placement, and handling. This reduces the probability of door displacement on the central beam 100 and the probability of misalignment between the door and the opening of the enclosure. This dimensional range is calculated to ensure sufficient space for the foaming material to flow in and form a robust structure, without affecting the strength of the reinforcing member 200 itself due to an excessively wide spacing between the two reinforcing walls 210. It ensures that the foaming material can better fill the limiting groove 230, avoiding incomplete filling (empty bubbles) caused by narrow space or poor flow. Empty bubbles severely affect the structural strength and insulation effect of the central beam 100.

[0037] Furthermore, in this embodiment, the distance between the two reinforcing walls 210 is 14 mm. This further avoids ensuring the wall thickness of the reinforcing walls 210, while also ensuring that the foamed material can better fill the limiting groove 230. In other embodiments, the distance between the two reinforcing walls 210 can also be 13.5 mm, 14.5 mm, or 15 mm.

[0038] The distance between the two second flanges 222 is 22mm to 28mm, that is, the distance between the two second flanges 222 is denoted as X3, 22mm≤X3≤28mm. Since the second flanges 222 are located outside the mounting groove 110, this solution limits the distance between the two second flanges 222 to 22mm to 28mm. This allows the foaming material to have enough space to flow between the two second flanges 222 and form a solid structure. This further enhances the adhesion of the reinforcing member 200 to the foam layer, thereby effectively resisting the bending and torsional stress generated during the opening and closing of the door, the placement of items, and the handling process. This reduces the probability of displacement of the door installed on the middle beam 100 and reduces the probability of misalignment between the door and the opening of the box.

[0039] Furthermore, in this embodiment, the distance between the two second flanges 222 is 25 mm, which further facilitates that the foaming material has sufficient space to flow between the two second flanges 222 and form a robust structure. In other embodiments, the distance between the two second flanges 222 can be 24 mm, 26 mm, 26.5 mm, or 27 mm.

[0040] Furthermore, the multi-segment limiting flange 220 also includes a third flange 223, which is located on the side of the second flange 222 away from the first flange 221. This allows the reinforcing member 200 to further cooperate with the foam layer, thereby further increasing the adhesion ability of the reinforcing member 200 to the foam layer.

[0041] In this embodiment, the third flange 223 extends along the extending direction of the first flange 221. However, this solution is not limited to this; in other embodiments, the extension of the third flange 223 may be in the opposite direction to the extending direction of the first flange 221.

[0042] Furthermore, in this embodiment, the first flange 221 extends outward from the width of the central beam 100 and from the mounting groove 110, the second flange 222 is parallel to the reinforcing wall 210, and the third flange 223 is parallel to the first flange 221. Of course, this solution is not limited to this; in other embodiments, the second flange 222 may intersect with the reinforcing wall 210, and / or the third flange 223 may intersect with the first flange 221.

[0043] Specifically, the angle between the reinforcing wall 210 and the first flange 221 is a right angle, and / or the angle between the first flange 221 and the second flange 222 is a right angle, and / or the angle between the second flange 222 and the third flange 223 is a right angle. However, this solution is not limited to this; in other embodiments, the angle between the reinforcing wall 210 and the first flange 221 is an acute angle, and / or the angle between the first flange 221 and the second flange 222 is an acute angle, and / or the angle between the second flange 222 and the third flange 223 is an acute angle.

[0044] Optionally, the reinforcing member 200 further has a connecting wall 240, which connects the two reinforcing walls 210. The connecting wall 240 is provided with a first fastening hole, and the middle beam 100 is provided with a second fastening hole corresponding to the first fastening hole. Fasteners pass through the first fastening hole and the second fastening hole in sequence to fasten the reinforcing member 200 and the middle beam 100 together. It can be understood that this solution connects the reinforcing member 200 and the middle beam 100 by having fasteners pass through the first fastening hole and the second fastening hole in sequence. The fastener is equivalent to a central shaft, thereby ensuring the relative position between the connecting wall 240 and the middle beam 100, that is, ensuring the relative position between the reinforcing member 200 and the middle beam 100, improving the positional fit accuracy between the middle beam 100 and the reinforcing member 200, further ensuring that the door hinge installed on the reinforcing member 200 is installed in place, and reducing the probability of misalignment between the door and the access opening.

[0045] In this design, a connecting wall 240 connects the two reinforcing walls 210, which increases the strength of the reinforcing member and reduces the probability of deformation and displacement of the reinforcing member 200. However, this design is not limited to this; in other embodiments, the connecting wall 240 may be omitted, and the reinforcing wall 210 may be directly connected to the central beam 100.

[0046] Furthermore, the reinforcing member 200 is formed using an integral molding process, which can improve the strength of the reinforcing member 200 and thus reduce the probability of deformation and displacement. Of course, this solution is not limited to this; in other embodiments, the reinforcing member 200 can also be formed by welding.

[0047] Optionally, the reinforcing member 200 can be made of iron, which helps reduce production costs. Of course, this solution is not limited to this; in other embodiments, the reinforcing member 200 can also be made of steel.

[0048] In this embodiment, the fastener is a rivet, that is, the connecting wall 240 is riveted to the central beam 100. Of course, in other embodiments, the fastener can also be a screw.

[0049] Optionally, to increase the connection strength between the reinforcing member 200 and the central beam 100, the connecting wall 240 in this embodiment is riveted to the central beam 100. However, this embodiment is not limited to this; in other embodiments, the connecting wall 240 may also be welded to the central beam 100.

[0050] Reference Figure 1 and Figure 3 Furthermore, at least one reinforcing member 200 is provided at each end of the mounting groove 110, and the reinforcing member 200 at the end of the mounting groove 110 is provided with an extension section 250 extending outward from the mounting groove 110. Each side of the extension section 250 has at least one reinforcing part extending laterally towards the mounting groove 110. The provision of the reinforcing part can increase the contact area of ​​the mounting section 250, thereby helping to reduce the probability of deformation of the mounting section 250.

[0051] Specifically, the extension section 250 is connected to the connecting wall 240, and the extension section 250 and the connecting wall 240 are respectively provided with hinge mounting holes for door hinge installation.

[0052] Furthermore, in the lateral direction of the mounting groove 110, the extension section 250 is provided with two hinge mounting holes at intervals. Specifically, the two hinge mounting holes on the extension section 250 are an upper hinge hole and a lower hinge hole. When the refrigerator is a cross-door refrigerator, the upper refrigerator door is installed with the upper hinge hole, and the lower refrigerator door is installed with the upper hinge hole. When the refrigerator is a French door refrigerator, the upper refrigerator door is installed with the upper hinge hole.
