Description

Technical Field

[0001] This utility model relates to the field of refrigerator ice-making technology, and in particular to a false beam fine-tuning device and a refrigerator. Background Technology

[0002] As consumers' demands for the quality of home appliances continue to rise, refrigeration equipment such as refrigerators and freezers are rapidly developing towards larger capacity, built-in designs, high-end features, refined craftsmanship, and aesthetic appeal. Especially in the mid-to-high-end market, refrigerators and freezers are no longer just functional cold storage devices, but have become an important part of the aesthetic design of kitchen spaces. Therefore, users have placed higher demands on the flatness of the refrigerator's appearance, the consistency of its seams, and the neatness of its surface.

[0003] Under this development trend, the dummy beam, as a key component connecting the inner liner and the cabinet structure, directly affects the overall appearance and sophistication of the refrigerator. However, existing refrigerators or freezers typically use a rigid snap-fit ​​connection between the dummy beam and the inner liner, making further adjustments difficult once assembled. Furthermore, it's challenging to compensate for minor surface unevenness caused by factors such as sheet metal stamping springback, injection molding shrinkage, processing errors, and foaming stress concentration. Especially in large-sized, ultra-thin-frame, zero-protrusion built-in refrigerators, any localized concavity or convexity in the dummy beam can lead to functional and aesthetic defects such as incomplete door closure, panel misalignment, and uneven seams, severely impacting the product's cooling and insulation performance, as well as its overall quality and user experience.

[0004] Therefore, in the traditional refrigerator or freezer assembly process, if the false beam cover plate is not installed properly on the first installation, it needs to be forcibly disassembled and reinstalled. The forced disassembly process can easily cause the clips to break or the sheet metal to deform, which in turn affects the life of refrigerator parts and assembly efficiency.

[0005] In addition, existing refrigerators or freezers lack an active leveling mechanism for their false beam covers. This is especially true for large-sized built-in refrigerators, where it is difficult to ensure that the surface of the long false beam cover is flush with the inner liner end face along its entire length, as well as the stability of the false beam flatness under mass production. Utility Model Content

[0006] This utility model proposes a false beam fine-tuning device and a refrigerator to solve the technical problem that it is difficult to adjust local concave or convex defects after the false beam of a traditional refrigerator is assembled into the inner liner.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0008] This utility model provides a dummy beam fine-tuning device, comprising:

[0009] The false beam base is fitted onto the inner liner of the refrigerator.

[0010] The false beam cover plate is installed on the working end of the false beam base facing the outside of the refrigerator through several fine-tuning components;

[0011] The fine-tuning component is connected between the dummy beam base and the dummy beam cover plate. It is used to adjust the dummy beam cover plate to retract or extend relative to the working end when the dummy beam cover plate protrudes outward or inward relative to the working end, so that the dummy beam cover plate is adjusted to be flush with the working end.

[0012] Preferably, the dummy beam base includes:

[0013] The base frame is a hollow cuboid. One side of the base frame is the open side of the internal cavity of the base frame. The side of the base frame opposite to the open side is the first closed side. The opposite sides of the base frame located between the open side and the first closed side, parallel to the length direction of the base frame, are a pair of second closed sides.

[0014] One pair of extended portions are arranged parallel to each other on both sides of the end face of the first closed side facing away from the opening side along the length direction of the base frame. The other pair of extended portions and the first closed side form a receiving groove. The end face of the extended portion facing away from the opening side is the working end.

[0027] The fine-tuning nut is screwed onto the end of the adjusting screw that extends away from the receiving groove and abuts against the mounting boss;

[0028] When the fine-tuning nut is rotated in the forward and reverse directions, it can drive the limit buckle to move closer to or further away from the internal cavity, thereby causing the dummy beam cover plate to retract or extend relative to the working end.

[0034] In the initial state where the false beam cover plate is not assembled, the flip fastener is driven by the return torsion spring to remain abutting against the inner wall of the corresponding side extension;

[0035] When the false beam cover plate is assembled, it moves along the inner wall of the corresponding side extension of the corresponding connecting part to approach the internal cavity, thereby pushing the flip fastener to flip back and forth around the flip axis and engage with the positioning slot.

[0036] Furthermore, the false beam fine-tuning device also includes:

[0065] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following description is provided in conjunction with the appendix. Figure 1-9 The present invention will be further described in detail with reference to the embodiments.

[0066] Please refer to the following: Figure 1-8 The dummy beam fine-tuning device provided by this utility model includes:

[0067] The false beam base 1 is mounted on the inner liner 6 of the refrigerator; the false beam cover 2 is installed on the working end A of the false beam base 1 facing the outside of the refrigerator through several fine adjustment components 3; the fine adjustment components 3 are used to adjust the false beam cover 2 to retract or extend relative to the working end A when the false beam cover 2 protrudes outward or inward relative to the working end A, so that the false beam cover 2 is adjusted to a position that is flush with the working end A.

[0068] The dummy beam fine-tuning device provided by this utility model is provided at the connection between the dummy beam cover plate 2 and the dummy beam base 1. The fine-tuning component 3 can adjust the retraction or extension of the dummy beam cover plate 2 relative to the working end A of the dummy beam base 1 when the dummy beam cover plate 2 protrudes outward or inward. This realizes active leveling of the dummy beam after assembly, corrects the bending, twisting or local unevenness of the dummy beam caused by processing errors or foaming stress, and avoids damage to parts due to the need for disassembly and reassembly if the dummy beam cover plate 2 is not installed properly at the first time.

[0069] Please refer to the following: Figure 1-8 In one embodiment of the dummy beam fine-tuning device provided by this utility model, the dummy beam base 1 includes:

[0070] The base frame 11 is a hollow cuboid. One side of the base frame 11 is an open side 111 that opens the internal cavity C of the base frame 11. The side of the base frame 11 opposite to the open side 111 is a first closed side 112. The opposite sides of the base frame 11 located between the open side 111 and the first closed side 112 and parallel to the length direction of the base frame 11 are a pair of second closed sides 113.

[0071] One pair of extension portions 12 are arranged parallel to each other along the length direction of the base frame 11 on both sides of the end face of the first closed side 112 facing away from the open side 111. The pair of extension portions 12 and the first closed side 112 form a receiving groove D. The end face of the extension portion 12 facing away from the open side 111 is the working end A of the above-mentioned false beam base 1 facing the outside of the refrigerator.

[0072] The false beam cover plate 2 is a long strip with a length and shape that matches the receiving groove D, and is embedded in the receiving groove D.

[0073] The fine-tuning component 3 passes through the first closed side 112 and is connected through the first closed side 112 to the inner side of the second closed side 113 facing the inner cavity C and between the false beam cover plate 2.

[0074] Please refer to the following: Figure 1-8 In a preferred embodiment of the false beam fine-tuning device provided by this utility model, the false beam cover plate 2 includes:

[0075] The end cap 21 is rectangular and its width matches the width of the receiving groove D. A pair of connecting portions 22 are arranged parallel to each other at opposite ends of the end cap 21 in the width direction and extend toward the same side of the end cap 21 in the thickness direction.

[0076] A pair of connecting portions 22 respectively abut against the opposite inner sidewalls of an outer extension portion 12, so that the false beam cover plate 2 is inserted into the receiving groove D by translating along the opposite inner sidewalls of an outer extension portion 12 through the pair of connecting portions 22.

[0077] Please refer to the following: Figure 1-8 In a preferred embodiment of the false beam fine-tuning device provided by this utility model, one pair of outer extensions 12 facing the inner wall of the receiving groove D are respectively flush with the inner wall of a pair of second closed sides 113 facing the inner cavity C, so that the receiving groove D and the inner cavity C have the same dimensions in the width direction of the false beam base 1.

[0078] Please refer to the following: Figure 1-8 In a preferred embodiment of the false beam fine-tuning device provided by this utility model, while the inner sidewalls of one pair of outer extensions 12 facing the receiving groove D are respectively flush with the inner sidewalls of a pair of second closed sides 113 facing the inner cavity C, the thicknesses (dimensions in the width direction of the false beam base 1) of the outer extensions 12 and the second closed sides 113 are the same, so that one pair of outer extensions 12 are respectively flush with the pair of second closed sides 113.

[0079] Please refer to the following: Figure 1-8 In a preferred embodiment of the false beam fine-tuning device provided by this utility model, the connecting part 22 is provided with a positioning slot 221. A clearance through hole 1121 matching the positioning slot 221 is provided on the first closed side 112 near the junction of the corresponding outer extension 12 and the second closed side 113. A mounting boss 13 is provided on the inner wall of the second closed side 113 facing the internal cavity C, and the mounting boss 13 is provided with a threaded through hole (not shown in the figure) matching the clearance through hole 1121.

[0080] Fine-tuning component 3 includes:

[0081] A snap-fit ​​bracket 31 is inserted into the clearance through hole 1121; a limiting snap-fit ​​32 is installed at one end of the snap-fit ​​bracket 31 that extends into the receiving groove D and cooperates with the positioning slot 221; an adjusting screw 33 is connected to the opposite end of the snap-fit ​​bracket 31 that extends into the internal cavity C, and the end of the adjusting screw 33 away from the snap-fit ​​bracket 31 is inserted into and screwed into the threaded through hole; a support spring 34 is sleeved on the adjusting screw 33 and abuts against the snap-fit ​​bracket 31 and the first closed side 112; a fine-tuning nut 35 is screwed onto the end of the adjusting screw 33 that extends out of the mounting boss 13 away from the receiving groove D and abuts against the mounting boss 13.

[0082] When the user holds a tool and inserts it into the internal cavity C of the base frame 11 from the opening side 111, and rotates the tool in both directions (tightening clockwise or loosening counterclockwise) to fine-tune the nut 35, the adjusting screw 33 can be driven to rotate downward and upward relative to the threaded through hole, thereby driving the buckle bracket 31 to move downward or upward along the clearance through hole 1121, while compressing or releasing the support spring 34, thereby driving the limit buckle 32 to move up and down closer to or away from the internal cavity C, so as to drive the false beam cover plate 2 to retract or extend relative to the working end A.

[0083] Please refer to the following: Figure 4-8 In a preferred embodiment of the false beam fine-tuning device provided by this utility model, the snap-fit ​​bracket 31 includes:

[0084] A bracket side plate 311; a bearing seat 312, located at one end of the bracket side plate 311; and a connecting seat 313, located at the other end of the bracket side plate 311 opposite to the bearing seat 312. The connecting seat 313, the bracket side plate 311, and the bearing seat 312 form a clearance groove E, and an adjusting screw 33 is connected to the end of the connecting seat 313 facing away from the bearing seat 312.

[0085] Limiting buckle 32 includes:

[0086] A flip shaft 321 is disposed in the relief groove E and is flipped and mounted on the bearing seat 312; a flip fastener 322 is mounted on the flip shaft 321; a reset torsion spring 323 is sleeved on the flip shaft 321 and abuts between the buckle bracket 31 and the flip fastener 322.

[0087] In the initial state before the dummy beam cover plate 2 is assembled, the flip fastener 322 is driven by the return torsion spring 323 to remain abutting against the inner wall of the corresponding side extension 12. When the dummy beam cover plate 2 is assembled, the corresponding connecting part 22 moves along the inner wall of the corresponding side extension 12 towards the internal cavity C, thereby pushing the flip fastener 322 to reciprocate around the flip axis 321 and engage with the positioning slot 221. At the same time, during the reciprocating flip of the flip fastener 322 around the flip axis 321, the positioning slot E provides sufficient space to avoid interference.

[0088] Please refer to the following: Figure 4-8 In a preferred embodiment of the false beam fine-tuning device provided by this utility model, the positioning slot 221 is a positioning through slot that passes through the connecting part 22 along the thickness direction. The flip fastener 322 is rectangular strip-shaped. One end of the flip fastener 322 in the length direction is a hinge end 3211 that is hinged to the flip shaft 321. The free end 3212 of the flip fastener 322 that can rotate around the flip shaft 321 has an inclined surface. The inclined surface is located on the side of the free end 3212 of the flip fastener 322 facing away from the internal cavity C, and is inclinedly connected between the two opposite sides of the flip fastener 322 facing away from and facing the internal cavity C. The connection between the inclined surface and the side of the flip fastener 322 facing the internal cavity C forms an angle of less than 90 degrees (forming a pointed end). The connection between the inclined surface and the other opposite side of the flip fastener 322 facing away from the internal cavity C forms an angle of more than 90 degrees, so that the longitudinal section of the flip fastener 322 is a right trapezoid.

[0089] In the initial state where the false beam cover plate 2 is not assembled, the flip fastener 322 is driven by the reset action of the reset torsion spring 323, thereby keeping the free end 3212 (the tip of the inclined surface) of the flip fastener 322, which can rotate around the flip axis 321, abutting against the inner wall of the corresponding side extension 12. At this time, the reset torsion spring 323 is in a naturally released extended state.

[0090] When the false beam cover plate 2 moves along the inner wall of the corresponding side extension 12 of the corresponding connecting part 22 and is embedded in the receiving groove D, the end of the corresponding connecting part 22 away from the end cover 21 first contacts the free end 3212 (the tip of the inclined surface) of the flip fastener 322 as the connecting part 22 moves closer to the inner cavity C. It continues to push the false beam cover plate 2 to drive the connecting part 22 to move closer to the inner cavity C, so that the end of the connecting part 22 away from the end cover 21 pushes the flip fastener 322 to flip around the flip axis 321 away from the corresponding side extension 12. During this process, the free end 3212 (the tip of the inclined surface) of the flip fastener 322 rotating around the flip axis 321 passes the end of the connecting part 22 away from the end cover 21 and abuts against the inner side of the connecting part 22 opposite to the other connecting part 22. At the same time, the reset torsion spring 323 is in a gradually compressed state to make way for the connecting part 22 to move closer to the inner cavity C.

[0091] Until the connecting part 22 moves close to the inner cavity C until the free end 3212 of the flip fastener 322 disengages from the inner side of the connecting part 22 and enters the positioning slot 221 area, the flip fastener 322, under the action of the reset torsion spring 323 switched to the release state, rotates around the flip shaft 321 close to the corresponding side of the outer extension 12 and flips until it is inserted into the positioning slot 221 and abuts against the inner side wall of the outer extension 12 facing the other outer extension 12, thus completing the insertion and engagement of the flip fastener 322 and the positioning slot 221, thereby realizing the pre-assembly of the false beam cover plate 2.

[0092] Please refer to the following: Figure 2-6 In a preferred embodiment of the dummy beam fine-tuning device provided by this utility model, the dummy beam fine-tuning device further includes:

[0093] A buffer sealing gasket 4 is disposed in the receiving groove D and abuts against the first closed side 112; a plurality of anti-condensation tubes 5 abut against the end cap 21 and the buffer sealing gasket 4.

[0094] Please refer to the following: Figure 2-6 In a preferred embodiment of the dummy beam fine-tuning device provided by this utility model, the buffer sealing gasket 4 is a compressible sponge gasket or silicone gasket. During the fine-tuning process of the fine-tuning component 3, the buffer sealing gasket 4 can adaptively fill the gap between itself and the end cap 21 through compression deformation according to the force of the end cap 21 pushing the anti-condensation tube 5 to squeeze the buffer sealing gasket 4 (i.e., the degree of compression of the buffer sealing gasket 4). It has both sealing and buffering functions, effectively preventing local stress concentration at the end cap of the dummy beam, and also effectively reducing air and cold leakage at the receiving groove D, reducing energy consumption and improving the overall energy efficiency.

[0095] Please refer to the following: Figure 2-6 In a preferred embodiment of the false beam fine-tuning device provided by this utility model, multiple pairs of fine-tuning components 3 are arranged at intervals along the length direction of the false beam base 1. A pair of mounting bosses 13 are respectively arranged on the opposite inner sides of a pair of second closed sides 113. Multiple pairs of threaded through holes, positioning slots 221 and clearance through holes 1121 are matched with the fine-tuning components 3. Each pair of threaded through holes is arranged at intervals along the length direction on a pair of mounting bosses 13. Each pair of positioning slots 221 is arranged at intervals along the length direction on a pair of connecting parts 22. Each pair of clearance through holes 1121 is arranged along the length direction at the position of the first closed side 112 near the junction of a pair of outer extensions 12 and a pair of second closed sides 113. Each pair of fine-tuning components 3 is respectively connected between the corresponding mounting boss 13 and the connecting part 22.

[0096] In other embodiments of the false beam fine-tuning device provided by this utility model, the mounting boss 13 can also be set intermittently, that is, multiple pairs of mounting bosses 13 are matched with fine-tuning components 3, and each pair of mounting bosses 13 are respectively set at intervals along the length direction on the opposite inner sidewalls of a pair of second closed sides 113 facing the inner cavity C.

[0097] In a preferred embodiment of the dummy beam fine-tuning device provided by this utility model, the dummy beam fine-tuning device further includes:

[0098] The linkage mechanism (not shown in the figure) is connected between the fine-tuning nuts 35 on the same side of each pair of fine-tuning components 3, and is used to make the limit buckles 32 on the same side of each pair of fine-tuning components 3 move synchronously.

[0099] In a preferred embodiment of the false beam fine-tuning device provided by this utility model, the linkage mechanism includes:

[0100] The adjusting ring connects to the fine-tuning nuts 35 on the same side of each pair of fine-tuning components 3 via a synchronous transmission structure (such as a gear connecting rod or a flexible shaft). When the adjusting ring is rotated, the movement of multiple limit buckles 32 on the same side of the fine-tuning components 3 can be controlled synchronously, thereby controlling the amount of retraction or extension of the false beam cover plate 2 relative to the working end A at multiple points along its length by the limit buckles 32 of multiple fine-tuning components 3, realizing the leveling operation of the false beam cover plate 2 with multi-point coordinated and uniform force distribution.

[0101] In a preferred embodiment of the false beam fine-tuning device provided by this utility model, the fine-tuning component 3 is automatically locked and positioned by the magnetic attraction of the permanent magnet after adjustment, preventing loosening caused by subsequent foaming vibration and improving structural stability.

[0102] Please refer to the following: Figure 1-2 The present invention also provides a refrigerator (not shown in the figure), which includes the above-mentioned false beam fine adjustment device, the false beam fine adjustment device being embedded in the opening end B of the inner liner 6 of the refrigerator.

[0103] Please refer to the following: Figure 1-2 In one embodiment of the refrigerator provided by this utility model, the working end A of the false beam base 1 is flush with the opening end B of the inner liner 6.

[0104] Please refer to the following: Figure 1-2 In a preferred embodiment of the refrigerator provided by this utility model, grooves 61 are provided on both sides of the opening end B of the inner liner 6. The opposite ends of a pair of extended portions 12 in the length direction serve as ribs that mate with the corresponding grooves 61 on both sides of the opening end B of the inner liner 6, guiding the accurate installation of the positioning false beam base 1 and preventing misalignment during assembly. The extended portions 12 and the grooves 61 can be initially secured with adhesive tape, without rigid securing or locking, solely for pre-positioning the false beam base 1 and the false beam cover 2. The structural firmness and stability of the false beam base 1 and the false beam cover 2 depend on the subsequent refrigerator body foaming process.

[0105] Please refer to the following: Figure 1-6 9. The method for fine-tuning the false beam of the refrigerator provided by this utility model is as follows:

[0106] Please see Figure 4First, multiple fine-tuning components 3 are installed on the dummy beam base 1, serving as the supporting base for the dummy beam cover plate 2. The fine-tuning components 3 are arranged at equal or varying distances along the length of the dummy beam base 1, and their number can be dynamically adjusted according to the length of the dummy beam cover plate 2 and the expected deformation. For example, for a dummy beam cover plate 2 with a length exceeding 1000mm, 5-11 fine-tuning components 3 can be set on each side to enhance the bending resistance of the middle section of the dummy beam cover plate 2 in the length direction.

[0107] Please see Figure 1-6 Then, the dummy beam base 1 is fixed to the outside of the inner liner 6 of the refrigerator (open end B), ensuring that the surface of the dummy beam base 1 is basically parallel to the surface of the open end B of the inner liner 6. Next, the buffer sealing gasket 4 and the anti-condensation tube 5 are installed sequentially in the receiving groove D of the dummy beam base 1 to improve the heat preservation and sealing performance of the receiving groove D and prevent condensation on the surface of the dummy beam cover 2. Then, the dummy beam cover 2 is snapped and embedded into the receiving groove D of the dummy beam base 1, and the dummy beam cover 2 is initially assembled and fitted with the open end B of the inner liner 6 by adjusting the various fine-tuning components 3.

[0108] At this point, it is necessary to check whether the false beam cover plate 2 and the opening end B of the inner liner 6 remain flush when the limiting buckle 32 of the fine-tuning component 3 are engaged. If the false beam cover plate 2 is found to have local concavity or convexity, it indicates that the false beam has undergone slight deformation due to its own length, initial stress, or processing errors. In this case, the false beam cover plate 2 can be reassembled by increasing the number of fine-tuning components 3 or adjusting their position until the entire false beam cover plate 2 is flush with the working end A of the false beam base 1 and the opening end B of the inner liner 6, thus achieving the flush adjustment of the false beam cover plate 2 in the pre-assembled state.

[0109] Please see Figure 5-6 Specifically, when the false beam cover plate 2 is concave, it indicates that the tension of the limiting buckle 32 at that location is too large. At this time, it should be rotated in the opposite direction (counterclockwise) and the fine-adjusting nut 35 should be loosened to release some tension and allow the false beam cover plate 2 to spring back to be flush with the working end A of the beam base. When the false beam cover plate 2 is convex, it indicates that the tension of the limiting buckle 32 in a local area is too small. At this time, it should be rotated in the forward direction (clockwise) and the fine-adjusting nut 35 should be tightened to enhance the clamping force of the limiting buckle 32 on the false beam cover plate 2, and pull the false beam cover plate 2 inward (closer to the internal cavity C) until the false beam cover plate 2 returns to be flush with the working end A of the beam base.

[0110] Please see Figure 1-2 Next, the refrigerator body foaming process is carried out. After foaming is completed, the flatness between the dummy beam cover plate 2, the dummy beam base 1, and the inner liner 6 is checked again. If the surface of the dummy beam cover plate 2 remains flat, it indicates that the dummy beam structure is stable and there is no obvious deformation during the foaming process; if the surface of the dummy beam cover plate 2 is uneven, it is necessary to further fine-tune the dummy beam cover plate 2 in the above manner.

[0111] By employing a dummy beam fine-tuning method, this invention achieves dual fine-tuning of the dummy beam during both the pre-assembly and post-foaming stages. This effectively compensates for deformation caused by processing errors, assembly stress, and foaming expansion forces, ensuring that the dummy beam remains in an ideal state of zero protrusion and full flatness, meeting the appearance consistency requirements of high-end embedded refrigerators. Simultaneously, it eliminates the need to increase the thickness of structural materials, aligning with the trend towards lightweight and low-carbon design, and possesses promising prospects for industrial application.

[0112] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Those skilled in the art should understand that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
