Description

Technical Field

[0001] This utility model belongs to the field of refrigerator sealing technology, and in particular relates to a high-compensation, low-height, energy-saving door seal. Background Technology

[0002] A refrigerator door seal is a refrigerator component used to seal the space between the refrigerator door and the refrigerator body. It has a sealing performance to ensure that the cold air inside the refrigerator does not leak out, while preventing hot air from entering the refrigerator, thereby maintaining a low temperature environment inside the refrigerator and extending the shelf life of food.

[0003] In some refrigerator products, the gap between the door and the refrigerator compartment often varies significantly after the door is closed. Ordinary door seals, due to their height and compensation limitations, are prone to creasing or failing to close properly, leading to poor sealing, cold air leakage, and increased energy consumption. Current solution: Change the height of the airbag. Disadvantages of the existing technology: It cannot handle refrigerators with large door-to-compartment gaps, and is prone to gaps or creasing, resulting in poor door sealing and cold air leakage. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems existing in the prior art and provide a high-compensation, low-height, energy-saving door seal. It is equipped with a high-compensation structure and is suitable for use in refrigerators with a large range of door-to-box spacing. After the refrigerator door is closed, the low airbag height of the door seal and the large compensation distance make it less prone to edge twisting in small door-to-box spacing, and the surface can still fit tightly against the cabinet in large door-to-box spacing, ensuring the refrigerator's seal. In addition, the wider main cross-section, in conjunction with the auxiliary airbag, increases the heat insulation width of the door seal and enhances its energy-saving effect.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A high-compensation, low-height, energy-saving door seal includes a magnetic stripe, a high-compensation structure located below the magnetic stripe, a side airbag located to the right of the magnetic stripe, a crossbeam located below the high-compensation structure, and a latch located below the crossbeam. The high-compensation structure is a cavity structure, and a square opening structure is provided at the lower inner end of the high-compensation structure. The lower end of the square opening structure is connected to the upper side of the crossbeam.

[0007] Furthermore, the ribs at the top of the side airbag are designed as a straight structure.

[0008] Furthermore, the width of the side airbag is greater than the width of the magnetic stripe airbag.

[0009] Furthermore, the magnetic stripe pouch is used for magnetic stripe mounting.

[0010] Furthermore, the large compensation structure has a first U-shaped connecting rib and a second U-shaped connecting rib on its left and right sides, respectively;

[0011] One end of the opening of the first U-shaped connecting rib is connected to the left end of the lower side of the magnetic stripe bag, and the other end of the opening of the first U-shaped connecting rib is connected to the square structure.

[0012] One end of the opening of the second U-shaped connecting rib is connected to the right end of the lower side of the magnetic stripe bag, and the other end of the opening of the second U-shaped connecting rib is connected to the upper side of the crossbeam.

[0013] The closed end of the second U-shaped connecting rib is connected to the side airbag.

[0014] Furthermore, the open end of the first U-shaped connecting rib is positioned opposite to the open end of the second U-shaped connecting rib.

[0015] Furthermore, the side airbag is provided with two connecting flanges, and an auxiliary airbag is provided at the end of the connecting flanges away from the side airbag.

[0016] Furthermore, the included angle between the two connecting flash edges is 60-150°.

[0017] Furthermore, a corner airbag is provided on the right side of the large compensation structure;

[0018] The corner airbags are located between the side airbags and the crossbeam.

[0019] Furthermore, the right side of the corner airbag has a corner connecting rib, which is a multi-segment bent structure;

[0020] One end of the corner connecting bar is connected to the side airbag, and the other end of the corner connecting bar is connected to the crossbeam.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This utility model provides a high-compensation, low-height, energy-saving door seal with a high-compensation structure, which allows the door seal to adapt to a large door-to-cabin distance. After the refrigerator door is closed, the low airbag height of the door seal strip and the large compensation distance prevent the door seal strip from twisting at small door-to-cabin distances, and ensures that the surface of the door seal sticks tightly to the cabinet at larger door-to-cabin distances, thus ensuring the refrigerator's airtightness. The square opening structure ensures that the door seal can still have good heat insulation performance and anti-condensation effect even with increased compensation. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] like Figure 1 As shown, a large-compensation, low-height energy-saving door seal is provided. The door seal 2 is disposed between the door body 4 and the box body 1. The door seal 2 includes a magnetic strip 8, a large-compensation structure 3, a side airbag 7, a crossbeam 9, and a latch 10.

[0029] Specifically, the large compensation structure 3 is integrally formed and disposed on the lower side of the magnetic stripe bag 8, the side airbag 7 is integrally formed and disposed on the right side of the magnetic stripe bag 8, the crossbeam 9 is integrally formed and disposed on the lower side of the large compensation structure 3, and the latch 10 is integrally formed and disposed on the lower side of the crossbeam 9.

[0030] The large compensation structure 3 is a hollow structure. A square opening structure 5 is integrally formed at the lower end of the inner side of the large compensation structure 3. The lower end of the square opening structure 5 is integrally formed and connected to the upper side of the crossbeam 9.

[0031] In this invention, the large compensation structure 3 on the door seal 2 increases its compensation performance, allowing it to better adapt to larger door-to-cabinet gaps. The door seal 2 is installed in the liner groove. Normally, when the refrigerator door 4 is closed, the door seal 2 is attracted to the surface of the cabinet 1 by the magnetic strip in the magnetic strip bag 8, with its upper surface adhering to the cabinet 1. However, when the door-to-cabinet gap is large, ordinary door seals, due to insufficient compensation, only partially contact the cabinet, or even fail to adhere to the cabinet due to excessive gaps. The large compensation structure 3 in the door seal 2 provided by this invention effectively solves this problem, allowing the door seal 2 to adapt to larger door-to-cabinet gaps and ensuring its sealing performance.

[0032] The square opening structure 5 enhances the heat insulation and anti-condensation performance of the door seal 2. Specifically, the door seal 2 is installed inside the liner groove. When the refrigerator door 4 is closed, the large compensation structure 3 of the door seal 2 causes the concave part of the compensation edge to be closer to the inside of the refrigerator. This makes the concave part more susceptible to the influence of cold air inside the refrigerator, thus forming condensation. The presence of this square opening structure 5 adds a layer of heat insulation to the concave part of the compensation edge, increasing the heat insulation performance of the door seal 2. At the same time, it reduces the influence of cold air inside the refrigerator on this area, reducing the possibility of condensation forming in this concave area and improving the anti-condensation performance of the door seal 2.

[0033] like Figure 1 As shown, in some embodiments of this utility model, a groove is provided on the door body 4, and the latch 10 is disposed in the groove.

[0034] like Figure 1 As shown, in some embodiments of this utility model, the ribs at the top of the side airbag 7 are designed as a straight structure;

[0035] The side airbag 7 can better adapt to smaller door gaps, improving the energy-saving effect of the door seal 2. The door seal 2 is installed inside the door liner. When the refrigerator door 4 is closed, the ribs on the side airbag 7 have a smooth, straight structure, allowing the door seal 2 to close the door easily without being blocked, even with small door gaps.

[0036] like Figure 1 As shown, in some embodiments of this utility model, the width of the side airbag 7 is greater than the width of the magnetic strip bag 8; the wider side airbag 7 structure can form a larger heat insulation width when the refrigerator door 4 is closed, which increases the heat insulation performance of the door seal 2 and improves the energy-saving effect of the door seal 2.

[0037] like Figure 1As shown, in some embodiments of this utility model, the magnetic strip bag 8 is used for magnetic strip installation; when the refrigerator door 4 is closed, under normal circumstances, the door seal 2 will be attracted to the surface of the cabinet 1 by the magnetic strip in the magnetic strip bag 8, and its upper surface will be in contact with the cabinet 1.

[0038] like Figure 1 As shown, in some embodiments of this utility model, the left and right sides of the large compensation structure 3 are respectively provided with a first U-shaped connecting rib 31 and a second U-shaped connecting rib 32; the large compensation structure 3 and the side airbag 7 are separated by the second U-shaped connecting rib 32.

[0039] Specifically, one end of the opening of the first U-shaped connecting rib 31 is connected to the left end of the lower side of the magnetic stripe bag 8, and the other end of the opening of the first U-shaped connecting rib 31 is connected to the square structure 5.

[0040] One end of the open end of the second U-shaped connecting rib 32 is connected to the right end of the lower side of the magnetic strip bladder 8, and the other end of the open end of the second U-shaped connecting rib 32 is connected to the upper side of the crossbeam 9.

[0041] The closed end of the second U-shaped connecting rib 32 is connected to the side airbag 7.

[0042] like Figure 1 As shown, in some embodiments of this utility model, the open end of the first U-shaped connecting rib 31 is arranged opposite to the open end of the second U-shaped connecting rib 32.

[0043] like Figure 1 As shown, in some embodiments of this utility model, the side airbag 7 is provided with two connecting flanges 71, and an auxiliary airbag 6 is provided at the end of the connecting flanges 71 away from the side airbag 7.

[0044] Specifically, two auxiliary airbags 6 are provided, which increases the heat insulation performance of the door seal 2 and improves its energy-saving effect. The door seal 2 is installed in the liner groove. When the refrigerator door 4 is closed, the auxiliary airbags 6 are in close contact with the cabinet 1 and the door 4, forming two sealed spaces. This increases the heat insulation width of the door seal, enhances its heat insulation performance, and reduces the refrigerator's energy consumption. Because the refrigerator main unit is located in different positions and the door liner interface structure is different, the requirements for heat insulation and assembly on each side of the refrigerator door are different. This door seal 2 adopts a butt welding method between the cross section with the auxiliary airbags 6 and the main cross section. This allows the auxiliary airbags 6 to be used in areas where the heat insulation performance requirement is greater, while only the main cross section is used on sides where the assembly effect requirement is more stringent. This allows the door seal 2 to achieve the expected heat insulation performance and energy-saving effect without the auxiliary airbags 6 being blocked, which would cause the door to not close tightly. This ensures the energy-saving effect and sealing performance of the door seal 2.

[0045] like Figure 1 As shown, in some embodiments of this utility model, the included angle between the two connecting flanges 71 is 60-150°.

[0046] like Figure 1 As shown, in some embodiments of this utility model, a corner airbag 11 is provided on the right side of the large compensation structure 3; the corner airbag 11 is located between the side airbag 7 and the crossbeam 9.

[0047] The right side of the corner airbag 11 has a corner connecting rib 12, which is a multi-segment bent structure;

[0048] One end of the corner connecting bar 12 is connected to the side airbag 7, and the other end of the corner connecting bar 12 is connected to the crossbeam 9;

[0049] The corner airbag 11 is located on the right side of the large compensation structure 3, between the side airbag 7 and the crossbeam 9. Specifically, the corner airbag 11 is located at the lower right corner of the door seal 2, and its right side has a corner connecting rib 12. The corner connecting rib 12 is close to the inner side of the door body 4, and the corner connecting rib 12 has a multi-segment bending structure. This setting not only ensures the stability of the installation of the door seal 2, but also the multi-segment bending structure design can have a certain deformation effect when the refrigerator door body 4 is opened or closed, thereby ensuring that it better adapts to the door-box spacing, and also ensuring the sealing performance of the door seal 2.

[0050] This utility model provides a high-compensation, low-height, energy-saving door seal with a high-compensation structure 3, which allows the door seal to adapt to a large door-to-cabin distance. After the refrigerator door is closed, the low airbag height of the door seal strip and the large compensation distance prevent the door seal strip from twisting at small door-to-cabin distances, and ensures that the surface of the door seal strip can fit tightly against the cabinet at larger door-to-cabin distances, thus ensuring the refrigerator's seal. The square opening structure 5 ensures that the door seal can also have good heat insulation performance and anti-condensation effect even with increased compensation.
