Description

Technical Field

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

[0002] Four-door refrigerators come in two types: one with a fixed vertical beam inside the refrigerator cavity, and the other using a hinged beam on the door instead of a vertical beam. The purpose of the vertical beam is to ensure that when the left and right doors are closed, the edges of the doors fit snugly against the surface of the vertical beam, thus ensuring a tight seal. The vertical beam contains a decondensation pipe to eliminate condensation on its surface, and a foam layer is filled inside the beam using a foaming process. The dense gaps in the foam layer trap a large amount of air. Because the vertical beam is constantly subjected to temperature changes, the gas inside will expand and contract. To prevent this from affecting the beam, a tiny vent hole is usually installed on the back of the vertical beam, connecting to the interior of the beam, allowing gas to enter and exit. To prevent liquid from seeping into the beam through this vent hole, the diameter is typically only a few millimeters or even smaller. Therefore, the drawback is that the foaming process involves filling the vertical beam with foaming agent through foaming pores, and the foaming agent forms a foam layer after foaming. However, the traditional vent is simply a hole set on the back of the vertical beam, and the pore size is very small. As a result, the foaming agent often blocks the vent after foaming, preventing gas from entering the vertical beam through the vent. Therefore, it is impossible to eliminate the pressure generated by the thermal expansion and contraction of the air inside the vertical beam. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a refrigerator vertical beam that can prevent the ventilation holes from being blocked.

[0004] The technical solution adopted by this utility model to solve the problem is: a refrigerator vertical beam, comprising: The beam has a foaming cavity on its front end face, foaming holes communicating with the foaming cavity on its surface, a vent hole extending through to the back of the beam on the bottom surface of the foaming cavity, an annular baffle surrounding the vent hole on the bottom surface of the foaming cavity, an installation position arranged along the height direction on the bottom surface of the foaming cavity, and an assembly part for mounting to a refrigerator cavity at the bottom of the back of the beam. A reinforcing liner is installed at the mounting position and covers the top of the annular retaining edge; A front cover that covers the foaming cavity, the foaming cavity being filled with a foaming layer, and a mounting groove provided on the front end face of the front cover, with a decondensation pipe arranged along the height direction in the mounting groove; A cover that fits into the mounting groove.

[0005] As a further improvement to the above technical solution, the bottom surface of the reinforcing lining abuts against the top of the annular retaining edge, and the top of the side of the annular retaining edge that is not directly opposite the foaming holes is provided with a breathable notch that runs through the inside and outside of the annular retaining edge.

[0006] As a further improvement to the above technical solution, several limiting grooves are arranged on the left and right sides of the mounting groove along the height direction, the bottom of the limiting groove is higher than the bottom surface of the mounting groove, and the dew removal pipe is arranged in the limiting groove.

[0007] As a further improvement to the above technical solution, the bottom surface of the mounting groove is provided with a plurality of first protrusions and first grooves at intervals along the height direction, the rear end face of the front cover is arched to form a second groove that cooperates with the first protrusion, the rear end face of the front cover is recessed to form a second protrusion that cooperates with the first groove and is spaced apart from the second groove, and the limiting groove is arranged on the first protrusion.

[0008] As a further improvement to the above technical solution, a plurality of partition platforms are arranged in the middle of the mounting groove along the height direction, and limiting grooves located on the left and right sides of the mounting groove are respectively arranged on the left and right sides of the partition platforms.

[0009] As a further improvement to the above technical solution, the inner walls on both sides of the mounting groove are provided with first hooks located on the first groove, and the two sides of the cover are provided with first locking holes for movably engaging with the first hooks.

[0010] As a further improvement to the above technical solution, the front end face of the beam is provided with an embedded edge surrounding the outer periphery of the foaming cavity, the outer periphery of the rear end face of the front cover is provided with an embedded groove, the embedded edge is movably inserted into the embedded groove, the top or bottom of the rear end face of the front cover is provided with a second hook extending toward the rear side, the foaming hole is provided at the top or bottom of the beam, and the second hook is movably engaged with the inner wall of the foaming hole.

[0011] As a further improvement to the above technical solution, a water-retaining slope is provided on the back of the beam above the assembly part. The top of the water-retaining slope is a slope that slopes downward toward the rear side of the beam, and the bottom of the water-retaining slope is an abutting plane. When the beam is installed on the refrigerator cavity, the abutting plane abuts against the bottom surface of the refrigerator cavity and covers the gap formed when the assembly part is assembled with the refrigerator cavity.

[0012] As a further improvement to the above technical solution, a locking groove for engaging with the partition is provided on one side of the back of the beam.

[0013] As a further improvement to the above technical solution, the mounting position includes a positioning pin located in the middle of the bottom surface of the foaming cavity along the height direction and elastic hooks located on both sides of the foaming cavity.

[0014] The beneficial effects of this utility model are as follows: By setting an annular baffle around the vent hole in the foaming cavity, and covering the top of the annular baffle with a reinforcing lining, when the foaming agent is filled into the foaming cavity through the foaming hole, the covering effect of the annular baffle and the reinforcing lining prevents the foaming agent from directly contacting the vent hole during the foaming process, thus preventing the vent hole from being blocked. This ensures that the air in the foaming cavity can be exchanged with the outside of the beam through the vent hole. Moreover, by setting the reinforcing lining, the strength of the vertical beam can be strengthened, and deformation and damage to the vertical beam can be avoided. Attached Figure Description

[0021] Reference Figures 1 to 5 A refrigerator vertical beam, comprising: The beam 10 has a foaming cavity 11 on its front end face, foaming holes 111 communicating with the foaming cavity 11 on its surface, a vent hole 12 extending through to the back of the beam 10 on the bottom surface of the foaming cavity 11, an annular baffle 13 surrounding the vent hole 12 on the bottom surface of the foaming cavity 11, an installation position arranged along the height direction on the bottom surface of the foaming cavity 11, and an assembly part 15 for mounting to a refrigerator cavity at the bottom of the back of the beam 10. A reinforcing lining 20 is installed at the mounting position, and the reinforcing lining 20 covers the top of the annular retaining edge 13; A front cover 30 covers the foaming cavity 11, the foaming cavity 11 is filled with a foaming layer, and the front end face of the front cover 30 is provided with an installation groove 31, and the installation groove 31 is provided with a decondensation pipe along the height direction. A cover 40 is fitted into the mounting groove 31.

[0022] By providing an annular baffle 13 surrounding the vent hole 12 within the foaming cavity 11, and with the top of the annular baffle 13 covered by a reinforcing lining 20, when foaming agent is filled into the foaming cavity 11 through the foaming hole 111, the covering effect of the annular baffle 13 and the reinforcing lining 20 prevents the foaming agent from directly contacting the vent hole 12 during the foaming process, thus preventing the vent hole 12 from being blocked. This ensures that the air inside the foaming cavity 11 can exchange with the outside of the beam 10 through the vent hole 12. Furthermore, by providing the reinforcing lining 20, the strength of the vertical beam can be enhanced, preventing deformation and damage to the vertical beam.

[0023] The gap between the reinforcing lining 20 and the annular baffle 13 is sufficient to allow the gas in the foaming chamber 11 to enter the space surrounded by the annular baffle 13 and then connect with the outside of the vertical beam through the vent hole 12. In order to further increase the flow of gas, it is preferable that the bottom surface of the reinforcing lining 20 abuts against the top of the annular baffle 13. The top of the side of the annular baffle 13 that is not directly opposite the foaming hole 111 is provided with a vent hole 14 that penetrates the inside and outside of the annular baffle 13. The vent hole 14 increases the air exchange volume of the space surrounded by the foaming chamber 11 and the annular baffle 13.

[0024] Further optimization is preferred, with several limiting grooves 32 arranged along the height direction on the left and right sides of the mounting groove 31. The bottom of the limiting groove 32 is higher than the bottom surface of the mounting groove 31. The decondensation pipe is arranged in the limiting groove 32. This structure can, firstly, restrict the position of the decondensation pipe to prevent it from moving, and secondly, elevate the decondensation pipe to avoid it directly contacting the bottom surface of the mounting groove 31.

[0025] Further optimization is preferred, where the bottom surface of the mounting groove 31 is provided with a plurality of first protrusions 33 and first grooves 34 spaced apart along the height direction. The rear end face of the front cover 30 is arched to form a second groove 35 that mates with the first protrusions 33, and the rear end face of the front cover 30 is recessed to form a second protrusion 36 that mates with the first groove 34 and is spaced apart from the second groove 35. The limiting groove 32 is arranged on the first protrusions 33. In this way, by alternating the arrangement of the first protrusions 33 and the first grooves 34 in the mounting groove 31, and by forming an alternating arrangement of the second grooves 35 and the second protrusions 36 on the rear side of the front cover 30, the front cover 30 is prevented from being a flat plate structure. The first protrusions 33, the first grooves 34, the second grooves 35, and the second protrusions 36 form a structure similar to reinforcing ribs, thereby strengthening the front cover 30 and preventing the front cover 30 from bending and deforming.

[0026] Further optimization is preferred, in which a plurality of partition platforms 37 are arranged along the height direction in the middle of the mounting groove 31, and the limiting grooves 32 located on the left and right sides of the mounting groove 31 are respectively arranged on the left and right sides of the partition platforms 37.

[0027] Further optimization is possible, whereby the face cover 40 and the front cover 30 can be fixed by bolts or glue. Preferably, the inner walls on both sides of the mounting groove 31 are provided with first hooks 311 located on the first groove 34, and the face cover 40 is provided with first locking holes 41 on both sides for engaging with the first hooks 311. Assembly can be completed quickly through the first hooks 311 and the first locking holes 41, without the need for bolts.

[0028] The beam 10 and the front cover 30 can also be fixed with glue or bolts. Considering the efficiency of assembly and to reduce the amount of bolts used, further optimization is made. The front end face of the beam 10 is provided with an embedded edge 101 surrounding the outer periphery of the foam cavity 11. The outer periphery of the rear end face of the front cover 30 is provided with an embedded groove 38. The embedded edge 101 is movably inserted into the embedded groove 38. The top or bottom of the rear end face of the front cover 30 is provided with a second hook 39 extending towards the rear. The foam hole 111 is provided at the top or bottom of the beam 10. The second hook 39 is movably engaged with the inner wall of the foam hole 111.

[0029] Considering that when the vertical beam is assembled into the refrigerator cavity through the assembly part 15 at the bottom of the beam body 10, there will be a gap between the assembly part 15 and the bottom surface of the refrigerator cavity. If water seeps into this gap, it will easily cause problems such as corrosion, deterioration and blackening. Therefore, it is preferable to provide a water-blocking slope 18 on the back of the beam body 10 above the assembly part 15. The top of the water-blocking slope 18 is a slope that slopes downward towards the rear side of the beam body 10, and the bottom of the water-blocking slope 18 is an abutting plane. When the beam body 10 is installed on the refrigerator cavity, the abutting plane abuts against the bottom surface of the refrigerator cavity and blocks the gap formed when the assembly part 15 is assembled with the refrigerator cavity, thereby reducing the problem of water seepage.

[0030] Considering that some refrigerators with vertical beams will have a partition in the middle of the cavity that cooperates with the vertical beam, it is preferable that a locking groove 19 for cooperating with the partition is provided on one side of the back of the beam 10.

[0031] Further optimization is preferred, where the mounting position includes a positioning pin 16 disposed at the center of the bottom surface of the foaming cavity 11 along the height direction and elastic hooks 17 located on both sides of the foaming cavity 11. The reinforcing liner 20 is provided with positioning pin holes for the pin to be inserted into. The elastic hooks 17 are movably engaged with the tops of both sides of the reinforcing liner 20, thereby positioning the reinforcing liner 20 by the positioning pin 16 and fixing the reinforcing liner 20 by the elastic hooks 17 during installation. In other embodiments, the mounting position can be other implementation structures, such as bolts, fixing ropes, etc.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
