Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a refrigeration equipment with a central beam that is not easily deformed. Background Technology

[0002] With the increasing popularity of side-by-side refrigerators, large-capacity side-by-side refrigerators have also become very popular. The layout of refrigerator compartments has also become more diverse to meet the needs of different people, such as side-by-side refrigerators with large freezer compartments and side-by-side refrigerators with large refrigerator compartments.

[0003] When a side-by-side refrigerator has a large capacity, its overall dimensions (height and depth) are also larger. Compared to a T-door refrigerator, which lacks a crossbeam for support, the central beam deforms due to the shrinkage of the foam material during refrigeration. This reduces the sealing surface between the refrigerator door seal and the central beam, leading to poor sealing, cold leakage, ice buildup, and other quality problems.

[0004] The two commonly used solutions are: first, thickening the central beam and adding reinforcing iron to increase its strength and offset deformation; second, adding an auxiliary door seal to the door body to improve the seal between the door seal and the central beam; and third, adding an auxiliary door seal to the door body to increase the sealing between the door seal and the central beam. This solution increases the cost and the complexity of the manufacturing process. Summary of the Invention

[0005] The purpose of this application is to provide a refrigeration device that limits the distance ratio between different positions of the freezing inner liner and the refrigeration inner liner, reduces the impact of the stress generated by the shrinkage of the foaming material on the central beam, and solves the problems of cold leakage and icing caused by the deformation of the central beam in the prior art.

[0006] To achieve one of the above-mentioned objectives, one embodiment of this application provides a refrigeration device, including a refrigerator inner liner and a freezer inner liner spaced apart along a first direction. The refrigerator inner liner includes a refrigerator section defining a refrigerator compartment, and the freezer inner liner forms a freezer compartment and an evaporator compartment that are interconnected. The freezer compartment and the evaporator compartment are arranged side by side along a direction perpendicular to the first direction. The freezer inner liner includes a freezer section defining the freezer compartment and an evaporator section defining the evaporator compartment. The distance between the freezer section and the refrigerator section is A, and the distance between the evaporator section and the refrigerator section is B, where B / A ≤ 1.5 or B / A = 30-35 mm.

[0007] As a further improvement of one embodiment of this application, foam material is filled between the freezing inner liner and the refrigeration inner liner;

[0008] The refrigeration equipment also includes a separator disposed between the evaporation section and the refrigeration section, the separator having smooth sides and not adhering to the foaming material.

[0009] As a further improvement of one embodiment of this application, the material separator is attached to the side of the evaporation section near the inner liner of the refrigerator.

[0010] As a further improvement of one embodiment of this application, the length of the material separator is not less than 1 / 3 of the height of the refrigeration equipment.

[0011] As a further improvement of one embodiment of this application, the material separator is disposed at the middle position in the height direction of the freezer inner liner.

[0012] As a further improvement of one embodiment of this application, it also includes a back plate disposed on the rear side of the refrigerated inner liner and the frozen inner liner; the distance between the rear end of the partition and the back plate is ≥ 1 / 3 of the distance between the frozen inner liner and the back plate.

[0013] As a further improvement of one embodiment of this application, it also includes a back plate disposed on the rear side of the refrigerator inner liner and the freezer inner liner; the material separator is fixed to the back plate and is provided with a material passage hole.

[0014] As a further improvement of one embodiment of this application, it also includes a U-shell formed as the side wall and top wall of the refrigeration equipment and a bottom plate disposed below the refrigerator inner liner and the freezer inner liner, wherein the cavity formed between the U-shell, the bottom plate, the back plate, the refrigerator inner liner and the freezer inner liner is a foam layer.

[0015] The refrigerated inner liner and the frozen inner liner are spaced apart in the horizontal direction. The bottom plate is provided with a filling hole. In the left and right direction, the distance between the filling hole and the material separator is ≥5mm.

[0016] As a further improvement of one embodiment of this application, a guide plate is also included, wherein the injection hole and the material separator are located on the same side of the guide plate in the left-right direction.

[0017] As a further improvement of one embodiment of this application, kraft paper is attached to both sides of the material separator.

[0018] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0019] The refrigeration equipment provided in this application includes a freezing inner liner and a refrigeration inner liner. Since the freezing inner liner needs to be equipped with an evaporator, it is divided into a freezing section that forms a freezing chamber and an evaporation section that forms an evaporator chamber. The distance A between the freezing section and the refrigeration inner liner should be less than the distance B between the evaporation section and the refrigeration inner liner. By controlling the value of B / A to be ≤1.5, the difference between A and B can be controlled, thereby reducing the thickness difference of the foamed layer between the refrigeration inner liner and the freezing inner liner and improving the impact of the stress generated when the foamed material shrinks on the central beam.

For example, a first flange may be referred to as a second flange, and similarly, a second flange may be referred to as a first flange, without departing from the scope of protection of this application.

[0034] This application provides a refrigeration device, such as... Figure 1 , 2 As shown, the device includes a refrigerator inner liner 1 and a freezer inner liner 2 spaced apart along a first direction. The refrigerator inner liner 1 includes a refrigerator section 11 that defines a refrigerator compartment 111. The freezer inner liner 2 forms a freezer compartment 211 and an evaporator compartment that are interconnected. The freezer compartment 211 and the evaporator compartment are arranged side by side along a direction perpendicular to the first direction. The freezer inner liner 2 includes a freezer section 21 that defines the freezer compartment 211 and an evaporator section 22 that defines the evaporator compartment. The distance between the freezer section 21 and the refrigerator section 11 is A, and the distance between the evaporator section 22 and the refrigerator section 11 is B. B / A ≤ 1.5, or B / A = 30~35mm.

[0035] Figure 1 The freezer inner liner 2 and the refrigerator inner liner 1 are arranged side by side in a horizontal direction. That is, the first direction is horizontal. In this application, the first direction is referred to as the left-right direction, and the left-right direction will be used to refer to the first direction below. The refrigerator compartment 111 formed by the refrigerator inner liner 1 and the freezer compartment 211 formed by the freezer inner liner 2 both open towards the front. That is, the side with the opening of the refrigerator compartment 111 and the freezer compartment 211 is the front, and the side away from the opening is the rear. Of course, the freezer inner liner 2 and the refrigerator inner liner 1 can also be arranged side by side in a vertical direction.

[0036] The refrigerated inner liner 1 also includes a first flange 12 disposed around the front opening of the refrigerated section 11, and the frozen inner liner 2 also includes a second flange 23 disposed around the front opening of the frozen section 21. The side of the refrigerated inner liner 1 near the frozen inner liner 2, the side of the frozen inner liner 2 near the refrigerated inner liner 1, the first flange 12 near the frozen inner liner 2, the second flange 23 near the refrigerated inner liner 1, and the foaming material filling the space between the frozen inner liner 2 and the refrigerated inner liner 1 (hereinafter referred to as the foaming material) form the central beam 3 of the refrigeration equipment.

[0037] This application limits the ratio of the distance B between the evaporator 22 and the refrigeration section 11 to the distance A between the freezing section 21 and the refrigeration section 11 to a maximum value, or limits the difference between B and A, thereby limiting the distance B between the evaporator 22 and the refrigeration section 11, which in turn limits the thickness of the foaming material between the evaporator 22 and the refrigeration section 11. This reduces the stress generated when the foaming material shrinks when the temperature of the freezing compartment 211 is very low, resulting in less shrinkage stress on the freezing inner liner 2 or the refrigeration inner liner 1, and thus the central beam 3 is less prone to deformation.

[0038] In some embodiments, the space between the freezing inner liner 2 and the refrigeration inner liner 1 is filled with foam material; the refrigeration equipment also includes a material separator 4 disposed between the evaporation section 22 and the refrigeration section 11, the material separator 4 having smooth sides and not adhering to the foam material.

[0039] The foam material filling the space between the freezing inner liner 2 and the refrigeration inner liner 1 is part of the aforementioned central beam 3, which is referred to in this application as the central beam 3 foam layer. The refrigeration equipment of this application has a spacer 4 that does not adhere to the foam material between the refrigeration section 11 and the evaporation section 22, which can separate the thicker portion of the central beam 3 foam layer between the evaporation section 22 and the refrigeration section 11. When the foam material shrinks, because the spacer 4 does not adhere to the foam material, the shrinkage of the foam material on both sides of the spacer 4 will create a gap between it and the spacer 4 under stress. The spacer 4 reduces the thickness of the foam material on either side of the spacer 4, making it less likely that the freezing inner liner 2 or the refrigeration inner liner 1 will deform during the shrinkage of the foam material, thus preventing deformation of the central beam 3.

[0040] In some embodiments, the spacer 4 is attached to the side of the evaporator 22 near the refrigerator liner 1 and can be fixed by means of adhesive, clips, etc. Since the temperature of the freezer compartment 211 is lower and the distance between the evaporator 22 and the refrigerator compartment 11 is larger, the spacer 4 is attached to the side of the foam layer of the central beam 3 near the freezer compartment 211. When the foam material shrinks due to cold, the foam material on the side of the spacer 4 near the refrigerator compartment 111 is stressed and shrinks towards the refrigerator compartment 111, forming a gap with the spacer 4. This will not cause deformation of the freezer liner 2 or the refrigerator liner 1, thus avoiding deformation of the central beam 3.

[0041] In some embodiments, the length of the partition 4 is not less than 1 / 3 of the height of the refrigeration equipment. The refrigeration equipment with the refrigerator inner liner 1 and the freezer inner liner 2 spaced apart in the horizontal direction is usually a side-by-side refrigerator. Since the refrigerator compartment 111 and the freezer compartment 211 are arranged side by side in a side-by-side refrigerator, the central beam 3 is longer and more susceptible to deformation due to cold. Therefore, the length of the partition 4 needs to be longer.

[0042] In some embodiments, the partition 4 is positioned at the center of the height of the inner liner 2. Since the central beam 3 is relatively long, the most severe deformation occurs in the center, thus positioning the partition 4 at the center of the height of the inner liner 2 is optimal.

[0043] In some embodiments, the refrigeration device provided in this application further includes a back plate 5 disposed on the rear side of the refrigeration inner liner 1 and the freezing inner liner 2; the distance between the rear end of the separator 4 and the back plate 5 is ≥ 1 / 3 of the distance between the freezing inner liner 2 and the back plate 5.

[0044] The space between the refrigerated inner liner 1 and the frozen inner liner 2 and the back panel 5 is filled with foam material to form a back foam layer. This back foam layer includes the foam material at the rear end of the central beam 3. That is, the cross-section of the back foam layer and the central beam 3 foam layer is T-shaped after combination. The spacer 4 is not only attached to the side of the evaporator 22 near the refrigerated compartment 111, but also extends rearward to a distance greater than or equal to one-third of the distance between the frozen inner liner 2 and the back panel 5.

[0045] Because the temperature in the freezer compartment 211 is low, not only will the foam material in the foam layer of the central beam 3 shrink due to the cold, but the foam material in the back foam layer on the rear side of the freezer inner liner 2 will also shrink due to the cold. Extending the partition 4 backward to separate part of the foam material in the back foam layer is more effective in reducing the shrinkage stress of the foam material. However, since the partition 4 will hinder the foaming and filling of the foam material during injection, the partition 4 cannot extend completely backward to the back plate 5. Space needs to be left between the partition 4 and the back plate 5 to allow the foam material to pass through.

[0046] The temperature in the freezer compartment 211 is low, so the thickness of the foam material on the back side of the freezer inner liner 2 needs to be designed to be thicker. Since the partition 4 is located on one side of the freezer inner liner 2, the distance between the freezer inner liner 2 and the back plate 5 is used as the basis for the distance design. If the distance between the rear end of the partition 4 and the back plate 5 is too small, it is easy to cause insufficient foaming and filling of the foam material, resulting in poor heat insulation effect and severe cold leakage of the refrigeration equipment.

[0047] In some embodiments, the refrigeration device provided in this application further includes a back plate 5 disposed on the rear side of the refrigerator inner liner 1 and the freezer inner liner 2; a material separator 4 is fixed to the back plate 5 and is provided with a material passage hole 41. In this embodiment, the space between the refrigerator inner liner 1 and the freezer inner liner 2 and the back plate 5 is also filled with foam material to form a back foam layer.

[0048] Unlike the aforementioned arrangement where the spacer 4 is spaced apart from the back plate 5, in this embodiment, the spacer 4 extends rearward to be fixed to the back plate 5. However, the spacer 4 has a material passage hole 41 for the foaming material to pass through, without affecting the diffusion and filling of the foaming material. In this case, the spacer 4 can simply be attached to the side of the evaporator 22 near the refrigerator compartment 111 in space. Of course, it can also be fixed to the freezer inner liner 2 by means of adhesive or other methods as described above.

[0049] Depending on the different positional relationships between the partition 4 and the back plate 5, the partition 4 can have various structures, such as... Figure 8 The middle section includes, in sequence, sheet-like structures (set in...) Figure 3 The separator 4 in the middle), the separator 4 extruded (set in the middle) Figure 5 4) Thicker injection-molded structure (set in the middle of the material separator) Figure 7 (Separator 4). Among them, the sheet structure is thinner and more suitable for being attached to the inner liner of the freezer 2. The injection-molded separator 4 can be processed to be thicker at one end as needed to be suitable for fixing to the back plate 5. The extruded separator 4 is not restricted.

[0050] In some embodiments, the refrigeration equipment provided in this application further includes a U-shell 6 formed as the side wall and top wall of the refrigeration equipment and a bottom plate 7 disposed below the refrigerator inner liner 1 and the freezer inner liner 2. The cavity formed between the U-shell 6, the bottom plate 7, the refrigerator inner liner 1 and the freezer inner liner 2 is a foam layer. The refrigerator inner liner 1 and the freezer inner liner 2 are spaced apart in the horizontal direction. The bottom plate 7 is provided with a filling hole 71. In the left-right direction, the distance between the filling hole 71 and the material separator 4 is ≥5mm.

[0051] In addition to the aforementioned foamed layers of the central beam 3 and the back foamed layer, the foamed layer also includes a top foamed layer located between the top of the refrigerated inner liner 1 and the frozen inner liner 2 and the top of the U-shell 6; two side foamed layers located between one side of the refrigerated inner liner 1 and the U-shell 6 and between the other side of the frozen inner liner 2 and the U-shell 6; and a bottom foamed layer located between the refrigerated inner liner 1 and the frozen inner liner 2 and the bottom plate 7. The bottom plate 7 is provided with an injection hole 71 for injecting foaming material into the foamed layer for foaming. The foaming material foams upward and to the left and right, which is affected by the partition 4. Therefore, the position of the injection hole 71 needs to be staggered from the position of the partition 4 to avoid uneven foaming of the foamed layers on both sides of the partition 4.

[0052] In some embodiments, the refrigeration device provided in this application further includes a guide plate 8, wherein the injection hole 71 and the material separator 4 are located on the same side of the guide plate 8 in the left-right direction. Specifically, as shown below... Figure 3 In the middle, the guide plate 8 is located below the material separator 4 and includes a first guide section 81 and a second guide section 82. The first guide section 81 is arranged approximately parallel to the material separator 4 and offset from the material separator 4 in the left and right directions. The second guide section 82 connects the first guide section 81 and the material separator 4.

[0053] Since the injection port 71 and the separator 4 are located on both sides of the guide plate 8, after the foaming material enters the foaming layer from the injection port, part of the foaming material foams from the side of the guide plate 8 away from the separator 4, and part of the foaming material flows sequentially through the first guide section 81 and the second guide section 82 to the separator 4. Because the temperature of the refrigeration compartment 111 is lower than that of the freezing compartment 211, the thickness of the back foaming layer on the rear side of the refrigeration inner liner 1 is lower, and the flowability of the foaming material is poor. Therefore, it is necessary to guide the flow through the guide plate 8.

[0054] In some embodiments, a material separator 4 is provided on both the side of the refrigerated inner liner 1 away from the frozen inner liner 2 and the side of the frozen inner liner 2 away from the refrigerated inner liner 1, so as to separate the connection between the side foam layer and the back foam layer, and also to reduce the impact of the shrinkage stress of the foam material on the inner liner, U-shell 6 and back plate 5.

[0055] In some embodiments, kraft paper is attached to both sides of the partition 4. The kraft paper has a smooth surface and can be directly attached to the surface of the partition 4 with double-sided tape or the like, which is convenient and low-cost.

[0056] In addition, materials or coatings with smooth surfaces, such as kraft paper, can be applied to the side of the refrigerated inner liner 1 near the frozen inner liner 2 and / or the side of the frozen inner liner 2 near the refrigerated inner liner 1. The application location and size can be referenced to the position and length of the partition 4.

[0057] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0058] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
