Technical Field

[0001] The present application relates to the field of refrigerator structures, and in particular to a high-barrier blister board for refrigerator doors. Background Art

[0002] The door structure of a refrigerator is crucial to improving the refrigeration effect and energy saving. Existing refrigerator doors mostly use simple insulation boards or single-layer plastic boards, which have poor insulation effects and easily lead to the leakage of cold air, thus affecting the refrigeration effect and energy consumption of the refrigerator.

[0003] A general refrigerator door frame is equipped with a sealing strip. Although there is an adsorption structure to provide pressure sealing when the refrigerator door is closed, its effect on blocking cold air is limited. After a long period of use, air leakage is likely to occur, affecting the energy consumption of the refrigerator. Summary of the invention

[0004] In order to improve the above-mentioned problems, the present application provides a high-barrier blister board for refrigerator doors.

[0005] The high barrier blister board for refrigerator door provided in the present application adopts the following technical solution:

[0006] A high-barrier blister plate for a refrigerator door, comprising a blister piece, wherein the blister piece is in a rectangular plate-shaped structure and has an inner groove corresponding to a sealing strip of a refrigerator door frame on one side;

[0007] A sealing plate is installed in the inner groove and is spaced apart from the groove wall of the inner groove by a preset distance of the width of the refrigerator door frame sealing strip. When the refrigerator is closed, the refrigerator door frame sealing strip is embedded in the inner groove, and the inner side of the refrigerator door frame sealing strip is respectively pressed against the groove wall of the inner groove and the outer wall of the sealing plate.

[0008] By adopting the above technical solution, when the refrigerator door and the refrigerator door frame are closed, the sealing strip on the refrigerator door frame contacts the blister part, and the sealing strip is embedded in the inner groove. When the refrigerator door and the refrigerator door frame are adsorbed on each other, the sealing strip is compressed by the suction force, and the sealing strip is compressed and expands to both sides, thereby pressing against the groove wall of the inner groove and the outer wall of the sealing plate to achieve the effect of sealing and heat preservation.

[0009] Optionally, the sealing plate is filled with heat-insulating material.

[0010] By adopting the above technical solution, the thermal insulation material has a thermal insulation effect, which can not only avoid heat transfer between the cold air in the refrigerator and the external heat, but also reduce the power consumption of the refrigerator.

[0011] Optionally, a sealing and heat-insulating film is provided at the connection between the sealing plate and the inner groove.

[0012] By adopting the above technical solution, the connection between the sealing plate and the inner groove is sealed with a sealing insulation film, which can prevent the thermal insulation material in the sealing plate from communicating with the inner groove, thereby ensuring the stability of the thermal insulation effect.

[0013] Optionally, the surfaces of the blister and the sealing plate are both covered with a layer of aluminum foil.

[0014] By adopting the above technical solution, the aluminum foil layer is used to improve the temperature blocking ability of the blister board, thereby further reducing the loss of cold air.

[0015] Optionally, a plurality of reinforcing ribs are provided on the sealing plate.

[0016] By adopting the above technical solution, the contact area of ​​the thermal insulation material in the sealing plate is increased by using reinforcing ribs, while the deviation of the thermal insulation material is limited, thereby extending the service life of the overall blister board.

[0017] Optionally, a plurality of the reinforcing ribs are arranged in a wave shape or a grid shape.

[0018] By adopting the above technical solution, the wavy or grid-shaped arrangement not only makes the overall reinforcing ribs more beautiful, but also increases the contact area and limit points between the thermal insulation material and the reinforcing ribs, further extending the service life of the overall blister board.

[0019] Optionally, the edges and corners of the blister and the sealing plate are both chamfered.

[0020] By adopting the above technical solution, the corners of the blister and the sealing plate are chamfered, which can ensure the safety of use and make the use more comfortable.

[0021] Optionally, the inner groove wall corners of the inner groove are configured as chamfers.

[0022] By adopting the above technical solution, the inner groove corners of the inner groove are set to be chamfered, which can make it easier for the refrigerator door frame to resist the groove wall of the inner groove when it is squeezed, thereby reducing the generation of gaps.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the refrigerator door and the door frame are closed, the sealing strip on the door frame contacts the blister, and the sealing strip is embedded in the inner groove. When the refrigerator door and the door frame are adsorbed on each other, the sealing strip is compressed by the suction force, and the sealing strip expands to both sides under pressure, thereby pressing against the groove wall of the inner groove and the outer wall of the sealing plate to achieve a sealing effect;

[0025] 2. The heat preservation material has a heat preservation effect, which can not only prevent the cold air in the refrigerator from transferring heat with the external heat, but also reduce the power consumption of the refrigerator;

[0026] 3. Use a sealing insulation film to seal the connection between the sealing plate and the inner groove to prevent the insulation material in the sealing plate from connecting with the inner groove, thus ensuring the stability of the insulation effect;

[0027] 4. Use reinforcing ribs to increase the contact area of ​​the insulation material in the sealing plate, while limiting the deviation of the insulation material and extending the service life of the overall blister board. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0038] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0039] The embodiment of the present application discloses a high-barrier blister board for a refrigerator door.

[0040] A high-barrier blister board for a refrigerator door is applied to the refrigerator door. A sealing strip is arranged at the door frame of the refrigerator. When the refrigerator door is closed, the sealing strip will contact the refrigerator door to form a sealing effect, so that the cold air in the refrigerator will not leak out. The high-barrier blister board of the present application is installed on the side of the refrigerator door close to the refrigerator door frame and contacts the sealing strip on the refrigerator door frame.

[0041] refer to Figure 1 As shown, the high barrier blister board includes a blister piece 1, which is a rectangular plate-like structure, namely, a blister board. The specific size corresponds to the size of the refrigerator door, and is therefore not limited and needs to be determined according to the size of the refrigerator door. The blister piece 1 is attached to a side of the refrigerator door close to the door frame, so that when the refrigerator door and the refrigerator door frame are closed, the sealing strip on the refrigerator door frame contacts the blister piece 1, and an inner groove 11 corresponding to the position of the sealing strip of the refrigerator door frame is provided on the side where the blister piece 1 contacts the sealing strip, and the depth of the inner groove 11 is less than the thickness of the sealing strip. When the refrigerator door is closed, the sealing strip is embedded in the inner groove 11.

[0042] The sealing plate 2 is installed in the inner groove 11 and has the same shape as the blister 1 , being a rectangular plate structure. The thickness of the sealing plate 2 is greater than the depth of the inner groove 11 and greater than the thickness of the sealing strip.

[0043] The sealing plate 2 and the groove wall of the inner groove 11 are spaced apart by a preset distance of the refrigerator door frame sealing strip width, so that when the refrigerator door and the refrigerator door frame are closed, the refrigerator door frame sealing strip is synchronously embedded in the inner groove 11, and the inner side of the sealing strip is respectively pressed against the groove wall of the inner groove 11 and the outer wall of the sealing plate 2.

[0044] Generally, refrigerator doors and refrigerator door frames are provided with adsorption structures with adsorption effects, such as magnets, torsion springs, etc., so that the refrigerator door and the refrigerator door frame are adsorbed to each other. Therefore, when the refrigerator door and the refrigerator door frame are adsorbed to each other, the sealing strip is compressed by the suction force, and the sealing strip is compressed and expands to both sides, thereby pressing against the groove wall of the inner groove 11 and the outer wall of the sealing plate 2 to further achieve the sealing effect.

[0045] Furthermore, the sealing plate 2 is filled with heat-insulating material, and the heat-insulating material can be made of fully compressed heat-insulating cotton. The light material will not increase the weight of the overall blister board, and at the same time has a heat-insulating effect, which can not only avoid heat transfer between the cold air in the refrigerator and the external heat, but also reduce the power consumption of the refrigerator.

[0046] Furthermore, a sealing insulation film 12 is provided at the connection between the sealing plate 2 and the inner groove 11. The sealing insulation film 12 is used to seal the connection between the sealing plate 2 and the inner groove 11 to prevent the thermal insulation material in the sealing plate 2 from being connected to the inner groove 11, thereby reducing the thermal insulation effect. Therefore, the sealing insulation film 12 can further ensure that cold air will not leak out, thereby ensuring the stability of the thermal insulation effect.

[0047] Furthermore, the surfaces of the blister 1 and the sealing plate 2 are covered with a layer of aluminum foil, and the aluminum foil layer is used to improve the temperature-blocking ability of the blister plate, further reduce the loss of cold air, and improve the thermal insulation effect.

[0048] In some embodiments, reference Figure 2 As shown, the sealing plate 2 is provided with a plurality of reinforcing ribs 3, which can increase the attachment capacity of the thermal insulation material and reduce the displacement of the thermal insulation material in the sealing plate 2. For example, if the refrigerator door is opened and closed for a long time, the thermal expansion and contraction may occur repeatedly, causing the thermal insulation material to shift or fall off. The reinforcing ribs 3 are used to increase the contact area of ​​the thermal insulation material in the sealing plate 2, and at the same time limit the displacement of the thermal insulation material, thereby extending the service life of the overall blister board.

[0049] Furthermore, a plurality of reinforcing ribs 3 are arranged in a wave shape or a grid shape. The wave shape or the grid shape arrangement not only makes the overall reinforcing ribs 3 more beautiful, but also increases the contact area and the limiting point between the thermal insulation material and the reinforcing ribs 3, and further prolongs the service life of the overall blister board.

[0050] Furthermore, a sealed cavity may be opened inside the reinforcing rib 3 , and the sealed cavity is also filled with a heat-insulating material to enhance the heat-insulating performance of the reinforcing rib 3 .

[0051] In some embodiments, the edges and corners of the blister 1 and the sealing plate 2 are chamfered. After the edges and corners of the blister 1 and the sealing plate 2 are chamfered, there are no sharp corners on their surfaces, so that when using the refrigerator door, the sharp corners will not be touched, ensuring the safety of use, while also making the use more comfortable.

[0052] Furthermore, the inner groove wall corners of the inner groove 11 are set as chamfers. The inner groove corners of the inner groove 11 are set as chamfers so that when the refrigerator door frame is squeezed, it can more easily resist the groove wall of the inner groove 11, thereby reducing the generation of gaps, reducing the loss of cold air, and improving the tightness of the closure of the refrigerator door and the refrigerator door frame.

[0053] In some embodiments, reference Figure 3 and Figure 4 As shown, the reinforcing rib 3 is provided with a limiting groove 31, and the sealing plate 2 is further provided with a detachable heat-insulating portion 21, and the heat-insulating portion 21 is provided with a disassembly opening 211, and the opening wall of the disassembly opening 211 is engaged with the limiting groove 31 of the reinforcing rib 3. The heat-insulating portion 21 can be made of any heat-insulating material such as polyurethane foam plastic, vacuum insulation board, etc., or other suitable heat-insulating materials. The number of the disassembly openings 211 is consistent with the number of the reinforcing ribs 3, and the width of the disassembly openings 211 is greater than the width of the reinforcing rib 3. Figure 3 Only a single reinforcing rib 3 and a part of the heat-insulating portion 21 are taken as an example, which does not mean that the number of the reinforcing rib 3 is only one.

[0054] When the insulation part 21 needs to be installed on the sealing plate 2, the insulation part 21 is covered on the blister 1 through the disassembly opening 211 and the reinforcing ribs 3 are matched one by one. The insulation part 21 passes through the disassembly opening 211, and then the insulation part 21 is loosened. The insulation part 21 loses support and slides downward under the influence of gravity. During the sliding process, the wall of the disassembly opening 211 is inserted into the limiting groove 31, thereby completing the installation.

[0055] When disassembly is required, since the width of the disassembly opening 211 is greater than the width of the reinforcing rib 3, the insulation part 21 can be pushed upward so that the mouth wall of the disassembly opening 211 is separated from the limiting groove 31, so that the insulation part 21 can be removed from the blister 1 for cleaning or replacement.

[0056] The insulation part 21 can provide additional insulation. The insulation part 21 covers the side of the sealing plate 2 close to the refrigerator door frame, so as to effectively prevent heat from being transferred to the sealing plate 2, thereby further maintaining the low temperature state inside the refrigerator. When the insulation part 21 is used for a long time, the refrigerator is frequently opened and closed, which will cause bacteria, mold or ice to grow on the insulation part 21. Therefore, the insulation part 21 can be taken out in a detachable manner when disassembly is required for cleaning, washing or replacement.

[0057] For further reference, Figure 3 and Figure 4 As shown, the reinforcing rib 3 is also slidably connected to a blocking piece 32. Specifically, a sliding groove is opened on the surface of the reinforcing rib 3, and the blocking piece 32 is located in the sliding groove and can slide along the sliding groove.

[0058] Among them, the opening direction of the sliding groove is along the length direction of the reinforcing rib 3, so when the baffle 32 slides, it slides along the length direction of the reinforcing rib 3. The main function of the baffle 32 is that when the insulation part 21 is installed close to the sealing plate 2, the baffle 32 slides toward the insulation part 21, so that it can jam the wall surface at the disassembly port 211 of the insulation part 21, further providing stable installation of the insulation part 21, avoiding the insulation part 21 from shaking due to gaps in the position during use, and improving stability.

[0059] When the heat preservation part 21 needs to be removed, the blocking piece 32 is first moved along the reinforcing rib 3 away from the heat preservation part 21 so that the blocking piece 32 is separated from the heat preservation part 21 and removed from the reinforcing rib 3 through the disassembly opening 211 without the restriction of the blocking piece 32 .

[0060] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
