[0037] In some common refrigeration devices such as refrigerators, a cooling cavity is generally formed inside the refrigeration device. A center beam structure is often installed horizontally on the cooling cavity to divide the cooling cavity into multiple storage chambers for storing different items respectively.
[0038] Due to different temperature requirements, the storage room has a refrigerator and a freezer. The temperature requirement of the freezer is lower. In some deep-freeze mode demand scenarios, the lowest temperature can reach -30°C. There is also a need to set up a central beam structure in the freezer. The two ends of the central beam structure are often overlapped on the two opposite inner walls of the storage room. However, at extremely low temperatures, the two ends of the central beam structure will shrink toward the middle of the central beam structure, increasing the gap between the door seal on the central beam structure and the box door, which is easy to reduce the cooling effect of the refrigeration device.
[0039] See also Figure 1 and Figure 2 The present invention provides a center beam structure, wherein the center beam structure 100 is used for a refrigeration device 200 having a cooling cavity 6. The center beam structure 100 includes a beam body 1 and a plurality of overlapping protrusions. Each overlapping protrusion extends from an end of the beam body 1 and is used to overlap a step surface 61 formed in the cooling cavity 6. Each overlapping protrusion has a length and width corresponding to the extension direction of the step surface 61.
[0040] At least one of the overlapping protrusions is configured as a first overlapping protrusion 2, and the first overlapping protrusion 2 includes at least two overlapping sections extending along the length direction of the beam body 1. In two adjacent overlapping sections, the thickness of the overlapping section away from the beam body 1 is smaller than the thickness of the overlapping section close to the beam body 1.
[0041] During the installation of the center beam structure 100, refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6, the two ends of the center beam structure 100 are often inserted into the slots 62 on the sides of the cooling cavity 6 respectively. The cooling cavity 6 is coated with foam material, and the foam material fills and connects the center beam structure 100 and the bottom wall of the slot 62. The overlapping protrusion is located on the outside of the cooling cavity 6, and the side of the overlapping protrusion close to the cooling cavity 6 is against the step surface 61 of the cooling cavity 6. A beam door seal is fixedly installed on the outside of the center beam structure 100, and an outer door seal is also fixedly installed on the outside of the cooling cavity 6. The beam door seal and the outer door seal are flush with each other. When the box door is closed, the box door is tightly against the center beam door seal and the outer door seal. When the refrigeration device 200 is in deep cooling mode, the lowest temperature in the cooling cavity 6 can reach -30°C, which is a large temperature difference from the temperature when the beam body 1 is formed or installed. The beam body 1 will shrink and deform along the length direction. After shrinking, the length of the beam body 1 becomes shorter, and the overlapping protrusion moves toward the middle side of the beam body 1. The overlapping protrusion is easy to fall off from the step surface 61 of the cooling cavity 6, so that the overlapping between the overlapping protrusion and the step surface 61 of the cooling cavity 6 is separated. When the cooling cavity 6 shrinks, it drives the beam body 1 and the beam door seal toward the inside of the cooling cavity 6. The outer side of the beam door seal and the outer side of the outer door seal are no longer flush, that is, a step is generated between the outer side of the beam door seal and the outer side of the outer door seal; when the box door is closed, a gap will be generated between the box door and the beam door seal, and the cooling cavity 6 will leak cold, reducing the cooling effect of the refrigeration device 200.
[0042] The technical solution of the present invention is to set two adjacent overlapping sections, and set the thickness of the overlapping section away from the beam body 1 to be smaller than the thickness of the overlapping section close to the beam body 1. When increasing the length of the overlapping protrusion, the space occupied in the thickness direction at the end of the beam body 1 where the first overlapping protrusion 2 is located is reduced, thereby reducing the interference between the first overlapping protrusion 2 and other components on the cooling cavity 6; when the two ends of the beam body 1 shrink toward the middle side of the beam body 1, the separation of the first overlapping protrusion 2 from the step surface 61 is reduced, thereby ensuring the stable overlap of the first overlapping protrusion 2 and the step surface 61, thereby reducing the movement of the door seal on the outside of the beam body 1 into the cooling cavity 6, ensuring the sealing between the door seal on the outside of the beam body 1 and the box door, reducing the cold leakage from the box door, and ensuring the cooling effect of the refrigeration device 200 as a whole.
[0043] The first overlapping protrusion 2 reduces the detachment of the overlapping connection between the beam body 1 and the step surface 61 of the cooling cavity 6. When the overlapping connection between one of the overlapping protrusions at one end away from the first overlapping protrusion 2 and the step surface 61 of the cooling cavity 6 is detached, the first overlapping protrusion 2 can reduce the displacement of the beam body 1 into the cooling cavity 6, thereby ensuring the stability of the installation of the beam body 1.
[0044] See also Figure 1 and Figure 2 Preferably, a first overlapping protrusion 2 is provided at both ends of the beam body 1, which enhances the overlapping length between the two ends of the beam body 1 and the step surface 61 of the cooling cavity 6, and reduces the separation of the two ends of the beam body 1 from the overlapping on the step surface 61 of the cooling cavity 6 when the beam body 1 shrinks along its length direction.
[0045] After the beam body 1 is installed, the length direction is from one end of the beam body 1 to the other end, the width direction is from the bottom side of the beam body 1 to the upper side of the beam body 1, and the width direction is from the outside of the opening of the cooling cavity 6 to the inside of the cooling cavity 6.
[0046] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , at least two of the overlapping sections include a first overlapping section 21 set away from the beam body 1 and a second overlapping section 22 set close to the beam body 1, and the thickness of the second overlapping section 22 is greater than the thickness of the first overlapping section 21. During the installation of the center beam structure 100, an installation gap 64 for the installation of the refrigerant pipe is formed between the end of the beam body 1 and the step surface 61. Common refrigerant pipes are round pipes or elliptical pipes. The step surface 61 and the refrigerant pipe are at odds with each other at the line connecting the tangent points. The step surface is mostly a plane, and there is a gap between the refrigerant pipe and the step surface 61. The gap between the refrigerant pipe and the step surface 61 gradually decreases from both sides of the refrigerant pipe to the middle of the refrigerant pipe.
[0047] When the second overlap section 22 is at its maximum length, there is only a very small gap between the second overlap section 22 and the refrigerant tube, which is used to reduce the deformation interference caused by the thermal barrier contraction between the second overlap section 22 and the refrigerant tube. By setting the thickness of the first overlap section 21 to be smaller than the thickness of the second overlap section 22, the first overlap section 21 can be placed between the refrigerant tube and the step surface 61 on the cooling cavity 6. By reducing the thickness of the first overlap section 21, the length of the first overlap section 21 can be increased without the first overlap section 21 contacting the refrigerant tube, thereby increasing the overlap length of the overlap protrusion and the cooling cavity 6. When the beam body 1 contracts due to cooling, the detachment of the overlap protrusion from the step surface 61 of the cooling cavity 6 is reduced.
[0048] The cross-sections of the first overlapping section 21 and the second overlapping section 22 along the length direction perpendicular to the beam body 1 are rectangular, and both the first overlapping section 21 and the second overlapping section 22 can be columnar.
[0049] At least two of the overlapping sections further include a third overlapping section, which is fixedly connected to the end of the first overlapping section 21. The thickness of the third overlapping section is less than or equal to the minimum thickness of the first overlapping section 21. The third overlapping section may be a thin metal plate with a thickness of 1-2 mm, and the third overlapping section is arranged along the length of the beam body 1. By configuring the third overlapping section as a thin metal plate, the metal strength of the third overlapping section can be ensured; the third overlapping section is placed between the refrigerant pipe and the stepped surface 61. The third overlapping section has a small thickness, which can reduce interference with the refrigerant pipe in the thickness direction, thereby reducing the movement of the refrigerant pipe in the thickness direction. When the beam body 1 contracts due to cooling, after both the first overlapping section 21 and the second overlapping section 22 detach from the step surface 61 of the cooling cavity 6, the third overlapping section can continue to overlap the step surface 61 of the cooling cavity 6, ensuring continuous overlap between the two ends of the center beam structure 100 and the step surface 61 of the cooling cavity 6. The third overlapping member can be a plurality of thin metal rods, in which case the diameter of the third overlapping member is set to be less than or equal to the minimum thickness of the first overlapping section 21.
[0050] See also Figure 1 、 Figure 7 and Figure 8 Specifically, the length of the second overlapping section 22 is about 5.9 mm, and the length of the first overlapping section 21 is 2 mm-3 mm, so that the length of the first overlapping protrusion is 7.9 mm-8.9 mm.
[0051] The end of the first overlapping section 21 has a relief surface 211; the thickness of the first overlapping section 21 gradually decreases in a direction away from the beam body 1, so that the relief surface 211 is inclined to avoid the refrigerant pipe disposed in the cooling cavity 6. By arranging the thickness of the first overlapping section 21 to gradually decrease in the direction of extension of the end of the beam body 1, the structural strength of the first overlapping section 21 can be ensured and deformation of the first overlapping protrusion 2 can be reduced.
[0052] The curvature of the avoidance surface 211 opens toward the middle of the beam body 1 . When the beam body 1 is subjected to a pulling force toward the cooling cavity 6 , the curvature of the avoidance surface 211 can reduce the deformation of the first overlapping section 21 and increase the structural strength of the first overlapping section 21 .
[0053] The curvature of the avoidance surface 211 opens away from the beam body 1 , so that the curvature of the avoidance surface 211 fits closely to the outside of the refrigerant pipe, thereby increasing the length of the first overlap section 21 while ensuring that the first overlap section 21 does not collide with the refrigerant pipe.
[0054] See also Figure 3 、 Figure 4 and Figure 6 The overlapping protrusion is provided at one end of the beam body 1 in the thickness direction, and at the other end of the beam body 1 in the thickness direction, an arc connecting surface 11 is provided between the end face and the side face of the beam body 1, and the arc radius of the arc connecting surface 11 is not greater than 10mm. Furthermore, the radius of the arc connecting surface 11 can be 9mm-10mm; the radius of the arc connecting surface 11 can be set to 9.5mm.
[0055] The cooling cavity 6 is mostly formed by vacuum forming, and the connections between adjacent surfaces of the cooling cavity 6 are mostly arc surfaces, that is, the cross-section of the angle inside the cooling cavity 6 is mostly rounded, and slots 62 are provided on the two opposite inner side surfaces of the cooling cavity 6. The parts at both ends of the beam body 1 are used to be inserted into the slots 62, and the cross-section of the inner corners of the slots 62 is rounded. By providing the arc connecting surface 11, when the parts at both ends of the beam body 1 are inserted and installed in the slots 62, the arc connecting surface 11 can be made to fit the inner corners of the slots 62, thereby reducing the gap between the end of the beam body 1 and the bottom wall of the slot 62, and reducing the leakage of cold air at the end of the beam body 1.
[0056] The radius of the inner corner of the slot 62 is generally about 10 mm. Setting the radius of the arc connection surface 11 to 10 mm can effectively ensure the fit between the arc connection surface 11 and the inner angle of the slot 62. When the radius of the inner corner of the slot 62 is 9 mm, the radius of the arc connection surface 11 can also be set to 9 mm according to actual needs.
[0057] At least one positioning member is provided at each end of the beam body 1. Each positioning member is inserted into a positioning slot 63 provided on the corresponding inner wall of the cooling cavity 6. The number of positioning members at each end of the beam body 1 can be one, two, or more. After the positioning members at both ends of the beam body 1 are inserted into the positioning slot 63, movement of the beam body 1 relative to the cooling cavity 6 is reduced, thereby achieving positioning and securing of the beam body 1.
[0058] See also Figure 6 、 Figure 7 and Figure 8, at least two positioning members are provided at one end of the beam body 1; the common inner side wall material of the cooling cavity 6 is relatively soft and has a certain deformation ability. Preferably, at least one positioning member includes a first positioning member 12 and a second positioning member 13, and at least one of the first positioning member 12 and the second positioning member 13 is respectively provided at one end of the beam body 1, and a positioning groove 63 is separately provided on the side wall of the cooling cavity 6 relative to each of the first positioning member 12 and each of the second positioning member 13; after the first positioning member 12 and the second positioning member 13 are respectively inserted into different positioning grooves 63, the stability of the installation of the beam body 1 is further improved. When the beam body 1 has a tendency to rotate, the first positioning member 12 and the second positioning member 13 are not easy to fall out of the positioning groove 63, which reduces the rotation of the beam body 1 and can limit the degree of freedom of the beam body 1.
[0059] The first positioning member 12 and the second positioning member 13 are provided at both ends of the beam body 1 , which further improves the installation stability of the beam body 1 .
[0060] The number of the positioning members at both ends of the beam body 1 can be three, four or more respectively. By inserting the positioning members into different positioning grooves 63 , the insertion stability of the two ends of the beam body 1 can be further improved.
[0061] The first positioning member 12 is a positioning column arranged in the length direction, and the first positioning member 12 is a hollow column, which reduces the weight of the first positioning member 12 while ensuring the structural strength of the first positioning member 12.
[0062] The beam body 1 includes an upper cover 3, a lower cover 4, and foam 5. A mounting cavity is formed between the upper and lower covers 3 and 4, and the foam 5 is disposed within the mounting cavity. The upper and lower covers 3 and 4 can be separated to facilitate filling the mounting cavity with the foam 5. The foam 5 is a thermal insulation sponge that improves the thermal insulation performance of the beam body 1.
[0063] Optionally, the beam body 1 is a hollow column to ensure the structural strength of the beam body 1. One end of the beam body 1 has an opening, and the foam 5 is filled in the beam body 1. After the foam 5 is installed, the opening at the end of the beam body 1 is sealed to prevent the foam 5 from falling out of the beam body 1.
[0064] The upper cover 3 and the lower cover 4 are arranged sequentially along the width direction, and both have the arc connecting surface 11. The lower side of the upper cover 3 has a first fixing ring 31 and a second fixing ring 32 arranged sequentially along the width direction. The first fixing ring 31 and the second fixing ring 32 are integrally connected, and the outer cross-section of the second fixing ring 32 is smaller than the outer cross-section of the first fixing ring 31, so that a step is formed between the first fixing ring 31 and the second fixing ring 32. The upper side of the lower cover 4 has a third fixing ring 41. The outer side of the second fixing ring 32 has a retaining groove 321. Multiple retaining grooves 321 are provided along the circumference of the second fixing ring 32. The inner side of the third fixing ring 41 has a fixed retaining block 411. Multiple retaining blocks 411 are provided around the circumference of the third fixing ring 41, and each retaining block 411 corresponds to and fits with the retaining groove 321.
[0065] After the second fixing ring 32 is inserted into the third fixing ring 41 , the clamping block 411 can be inserted into the clamping groove 321 , and the upper side of the third fixing ring 41 abuts against the lower side of the first fixing ring 31 , thereby achieving a clamping fixation between the upper cover 3 and the lower cover 4 .
[0066] An insertion rod 42 is also fixedly provided on the upper side of the lower cover 4. The insertion rod 42 is located on the inner side of the third fixing ring, and there are multiple insertion rods 42. The insertion rod 42 can be pressed against the inner side of the second fixing ring 32, thereby reducing the shaking of the second fixing ring 32 and improving the stability of the clamping of the second fixing ring 32.
[0067] See also Figure 6 、 Figure 7 and Figure 8 Two overlapping protrusions are provided at at least one end of the beam body 1; preferably, two overlapping protrusions are provided at both ends of the beam body, and the two overlapping protrusions are arranged sequentially along the width direction of the beam body 1. Preferably, two or more overlapping protrusions are provided at each end of the beam body 1. The provision of the overlapping protrusions increases the overlapping area between the center beam structure 100 and the stepped surface 61 of the cooling cavity 6, thereby improving the stability of the overlapping of the center beam structure 11.
[0068] The overlapping protrusions at both ends of the beam body 1 can be set to three, four or more. By increasing the number of the overlapping protrusions, the overlapping area between the central beam structure 11 and the step surface 61 of the cooling cavity 6 can be further increased, thereby reducing the pressure on the step surface 61 and improving the stability of the overlapping of the central beam structure 11.
[0069] The overlapping protrusions can all be first overlapping protrusions 2. The multiple first overlapping protrusions 2 arranged along the width direction of the beam body 1 can further improve the stability of the overlapping of the beam body 1 on the cooling cavity 6.
[0070] Some of the overlapping protrusions are provided on the upper cover 3, while the remaining overlapping protrusions are provided on the lower cover 4. The upper cover 3 and the lower cover 4 can each overlap on the stepped surface 61 of the cooling cavity 6, thereby improving the stability of the overlap between the upper cover 3 and the lower cover 4. Preferably, the overlapping protrusions on the upper cover 3 are all first overlapping protrusions 2, and the first overlapping protrusions 2 on the upper cover 3 are respectively provided at both ends of the upper cover 3; and the overlapping protrusions on the lower cover 4 are all first overlapping protrusions 2, and the first overlapping protrusions 2 on the lower cover 4 are respectively located at both ends of the lower cover 4.
[0071] Optionally, the overlapping protrusions may all be provided on the upper cover 3 , or the overlapping protrusions may all be provided on the lower cover 4 .
[0072] The beam body 1 is provided with a plurality of positioning members, some of which are provided on the upper cover 3 and the rest are provided on the lower cover 4. The upper cover 3 and the lower cover 4 can be snap-fitted and fixed to the inner wall of the cooling cavity 6 respectively.
[0073] Optionally, the positioning members may be provided on the upper cover 3, so as to snap-fit the upper cover 3 to the cooling cavity 6. Optionally, the positioning members may be provided on the lower cover 4, so as to snap-fit the lower cover 4 to the cooling cavity.
[0074] The first positioning member 12 is integrally fixedly connected to the upper cover 3, achieving a snap-fit fixation of the upper cover 3. The second positioning member 13 includes a first positioning block 131 and a second positioning block 132. The first positioning block 131 is integrally fixedly connected to the upper cover 3, and the second positioning block 132 is integrally fixedly connected to the lower cover 4. This improves the stability of the snap-fit fixation of the upper cover 3 within the cooling cavity 6 and achieves a snap-fit fixation of the lower cover 4 within the cooling cavity 6. The first positioning block 131 and the second positioning block 132 are located in the same positioning groove 63, which can limit the separation between the first positioning block 131 and the second positioning block 132, thereby limiting the separation between the upper cover 3 and the lower cover 4.
