Description

[0001] This utility model is a divisional application of patent application number 202421551280.0 filed on July 2, 2024, entitled "Refrigeration equipment and its enclosed door seal structure". Technical Field

[0002] This utility model relates to the field of door sealing technology for refrigeration equipment, and specifically to a refrigeration equipment. Background Technology

[0003] Door seals are commonly used between the cabinet and door of refrigeration equipment. Their main function is to effectively isolate the refrigeration equipment from the internal and external environments when it is closed, maintaining the low temperature and humidity inside the equipment. Specifically, they are mostly used in refrigeration equipment such as refrigerators and freezers.

[0004] Currently, most refrigerators use multi-airbag door seals, while freezers mostly use single-airbag door seals. Air convection exists inside the door seal, and long-term use of the compressed door seal will cause it to lose its elasticity, thus affecting the energy consumption of the refrigeration equipment. Utility Model Content

[0005] The purpose of this invention is to overcome the problem of increased energy consumption caused by convection inside the door seal in the existing technology, and to provide a refrigeration device and its encapsulated door seal structure, which has the function of reducing convection inside the door seal.

[0006] To achieve the above objectives, this utility model provides a covered door seal structure for a refrigeration device, comprising:

[0007] Door seal body, the door seal body comprising:

[0008] The snap-fit ​​part is used to engage with the snap-fit ​​groove of the door body;

[0009] Multiple airbags are disposed on the side of the snap-fit ​​portion away from its tip, and are designed to be compressed and deformed to fit and seal against the surface of the housing.

[0010] A strip-shaped filler is provided inside the airbag near the snap-fit ​​portion.

[0011] Optionally, the strip filler includes felt.

[0012] Optionally, the corners of the airbag near the housing are rounded.

[0013] Optionally, the inner wall of the airbag near the snap-fit ​​portion is provided with a thickened portion.

[0014] Optionally, the thickened portion is disposed on two inner walls adjacent to the connection side of the airbag and the snap-fit ​​portion.

[0015] On the other hand, this utility model also provides a refrigeration device, including:

[0016] The box has an opening on one side, and a refrigeration device is installed inside the box.

[0017] A door is provided on the opening side of the box and connected to the box. A snap-fit ​​groove is provided on the side of the door closest to the box.

[0018] An encapsulated door seal structure is disposed between the housing and the door to seal the space between the housing and the door and reduce gas convection.

[0019] Optionally, the encapsulated door seal structure includes:

[0020] Door seal body, the door seal body comprising:

[0021] The snap-fit ​​part is used to engage with the snap-fit ​​slot;

[0022] Multiple airbags are disposed on the side of the snap-fit ​​portion away from its tip, and are designed to be compressed and deformed to fit and seal against the surface of the housing.

[0023] A strip-shaped filler is provided inside the airbag near the snap-fit ​​portion.

[0024] Optionally, the strip filler includes felt.

[0025] Optionally, the corners of the airbag near the housing are rounded.

[0026] Optionally, the inner wall of the airbag near the snap-fit ​​portion is provided with a thickened portion, which is provided on two inner walls adjacent to the connection side of the airbag and the snap-fit ​​portion.

[0027] Through the above technical solution, the refrigeration equipment and its encapsulated door seal structure provided by this utility model are engaged with the door body through the engagement groove of the engagement part, so that multiple airbags are squeezed between the door body and the box body. At the same time, the strip filling material inside the airbag near the engagement part is also squeezed. Since the strip filling material is fully placed inside the airbag, it can effectively reduce the convection of gas inside the airbag, that is, effectively reduce heat conduction and improve the heat preservation effect of the door seal body. At the same time, the strip filling material can also support the airbag to maintain the maximum deformation range of the airbag, thereby ensuring the reset effect of the airbag.

[0035] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0036] Figure 1 This is a schematic diagram of the enclosed door seal structure of a refrigeration device according to one embodiment of the present invention. Figure 1 In this design, the encapsulated door seal structure may include a door seal body 3 and a strip-shaped filler 4. Specifically, the door seal body 3 may include a snap-fit ​​portion 1 and multiple airbags 2.

[0037] The snap-fit ​​portion 1 is used to engage with the snap-fit ​​groove 9 of the door body 8. Multiple airbags 2 are disposed on the side of the snap-fit ​​portion 1 away from its tip. Specifically, the snap-fit ​​portion 1 is triangular in shape, and therefore on the bottom side of the snap-fit ​​portion 1. The multiple airbags 2 are used to be compressed and deformed to fit and seal against the surface of the housing 7. Strip-shaped fillers 4 are filled inside the airbags 2 near the snap-fit ​​portion 1.

[0038] When the door seal structure needs to be installed, simply engage the snap-fit ​​part 1 of the door seal body 3 with the snap-fit ​​groove 9. When the door 8 is closed, multiple airbags 2 are compressed so that they fit tightly against both the housing 7 and the door 8, sealing the space between them. As the airbags 2 are compressed, the strip-shaped filler 4 is also simultaneously compressed and deformed, but remains fully inflated. The compression of the strip-shaped filler 4 further increases its inflation level, effectively reducing the convection of gas inside the airbags 2.

[0039] Traditional refrigeration equipment, such as refrigerators, uses multi-bladder door seals, while freezers typically use single-bladder door seals. Air convection occurs inside these seals, and prolonged use and compression can cause them to lose elasticity, thus affecting the energy consumption of the refrigeration equipment. In this embodiment of the invention, a strip-shaped filler 4 is used to fill the air bladder 2 near the latching part 1. This effectively reduces air convection inside the air bladder 2, thus reducing heat conduction and improving the insulation effect of the door seal body 3, thereby reducing the energy consumption of the refrigeration equipment. Simultaneously, the strip-shaped filler 4 also supports the air bladder 2 to maintain its maximum deformation range, ensuring its proper return to its original position.

[0040] In this embodiment of the present invention, the airbag 2 can include various forms known in the art, such as a magnetic stripe airbag, a main airbag, an auxiliary airbag, etc. Specifically, the strip-shaped filler 4 is disposed inside the airbag 2 near the latching part 1, that is, inside the main airbag 2. On the one hand, this can improve the reset elasticity of the main airbag 2, and on the other hand, it can effectively reduce the gas convection inside the door seal body 3.

[0041] In this embodiment of the present invention, the strip filler 4 may be made of a low thermal conductivity material. Specifically, the strip filler 4 may include felt, etc. Specifically, the felt material has a low thermal conductivity and does not melt with the extruded door seal body 3. After being formed with the door seal body 3, it can be removed and separated, thus having greater versatility and wider applicability. In addition, the felt material can fill the interior of the door seal body 3, eliminating internal gas convection and reducing heat conduction under steady-state conditions. At the same time, the felt material is a low thermal conductivity material, which also reduces heat mass transfer and improves the heat insulation performance of the door seal. When the door is closed, the felt material can deform synchronously under force, so that the door seal can be stably and closely attached to the box body 7 without interfering with the deformation of the door seal.

[0042] In this embodiment of the present invention, such as Figure 1 As shown, the corner of the airbag 2 near the housing 7 in the door seal assembly is set with an arc 5, that is, the edge of the airbag 2 that fits against the housing 7 is set with an arc 5. Specifically, this arc 5 structure can prevent the door 8 from twisting when closed, and can also make the door seal fit better against the housing 7.

[0043] In this embodiment of the present invention, such as Figure 1 As shown, the airbag 2 may include two thickened portions 6. Specifically, the thickened portions 6 are disposed on the inner wall of the main airbag 2.

[0044] A thickened portion 6 is provided on the inner wall of the airbag 2 near the locking part 1. The thickened portion 6 is provided on two side walls adjacent to the connection side of the airbag 2 and the locking part 1.

[0045] Thickened portions 6 are provided on the inner walls of the two sides adjacent to the main airbag 2 near the door body 8. The thickened portions 6 can effectively improve the compression support characteristics of the door seal, thereby improving the service life of the door seal.

[0046] In this embodiment of the present invention, the thickened portion gradually increases in thickness from the end of the housing 7 along the end of the door 8, so as to further improve the stability and support effect of the airbag 2 being compressed.

[0047] On the other hand, this utility model also provides a refrigeration device, specifically, such as Figure 1 As shown, the refrigeration equipment may include a housing 7, a door 8, and a cover-type door seal structure. Specifically, the housing 7 may include an opening and a refrigeration unit, and the door 8 may include a snap-fit ​​groove 9.

[0048] An opening is provided on one side of the enclosure 7, and a refrigeration unit is installed inside the enclosure 7. The door 8 is located on the opening side of the enclosure 7 and is connected to the enclosure 7. A snap-fit ​​groove 9 is provided on the side of the door 8 near the enclosure 7. A cover-type door seal structure is provided between the enclosure 7 and the door 8 to seal the space between the enclosure 7 and the door 8 and reduce gas convection.

[0049] The refrigeration unit is located inside the cabinet 7 to cool the interior of the cabinet 7. The enclosed door seal structure can seal the space between the door 8 and the cabinet 7, while reducing gas convection between the door 8 and the cabinet 7, which reduces heat conduction and thus effectively ensures the cooling effect inside the refrigeration equipment and reduces the energy consumption of the refrigeration equipment.

[0050] In this embodiment of the present invention, such as Figure 1 As shown, the encapsulated door seal structure may include a door seal body 3 and a strip-shaped filler 4. Specifically, the door seal body 3 may include a snap-fit ​​portion 1 and multiple airbags 2.

[0051] The snap-fit ​​portion 1 is used to engage with the snap-fit ​​groove 9 of the door body 8. Multiple airbags 2 are disposed on the side of the snap-fit ​​portion 1 away from its tip. Specifically, the snap-fit ​​portion 1 is triangular in shape, and therefore on the bottom side of the snap-fit ​​portion 1. The multiple airbags 2 are used to be compressed and deformed to fit and seal against the surface of the housing 7. Strip-shaped fillers 4 are filled inside the airbags 2 near the snap-fit ​​portion 1.

[0052] When the door seal structure needs to be installed, simply engage the snap-fit ​​part 1 of the door seal body 3 with the snap-fit ​​groove 9. When the door 8 is closed, multiple airbags 2 are compressed so that they fit tightly against both the housing 7 and the door 8, sealing the space between them. As the airbags 2 are compressed, the strip-shaped filler 4 is also simultaneously compressed and deformed, but remains fully inflated. The compression of the strip-shaped filler 4 further increases its inflation level, effectively reducing the convection of gas inside the airbags 2.

[0053] In this embodiment of the present invention, the airbag 2 can include various forms known in the art, such as a magnetic stripe airbag, a main airbag, an auxiliary airbag, etc. Specifically, the strip-shaped filler 4 is disposed inside the airbag 2 near the latching part 1, that is, inside the main airbag 2. On the one hand, this can improve the reset elasticity of the main airbag 2, and on the other hand, it can effectively reduce the gas convection inside the door seal body 3.

[0054] In this embodiment of the present invention, the strip filler 4 may be made of a low thermal conductivity material. Specifically, the strip filler 4 may include felt, etc. Specifically, the felt material has a low thermal conductivity and does not melt with the extruded door seal body 3. After being formed with the door seal body 3, it can be removed and separated, thus having greater versatility and wider applicability. In addition, the felt material can fill the interior of the door seal body 3, eliminating internal gas convection and reducing heat conduction under steady-state conditions. At the same time, the felt material is a low thermal conductivity material, which also reduces heat mass transfer and improves the heat insulation performance of the door seal. When the door is closed, the felt material can deform synchronously under force, so that the door seal can be stably and closely attached to the box body 7 without interfering with the deformation of the door seal.

[0055] In this embodiment of the present invention, such as Figure 1 As shown, the corner of the airbag 2 near the housing 7 in the door seal assembly is set with an arc 5, that is, the edge of the airbag 2 that fits against the housing 7 is set with an arc 5. Specifically, this arc 5 structure can prevent the door 8 from twisting when closed, and can also make the door seal fit better against the housing 7.

[0056] In this embodiment of the present invention, such as Figure 1 As shown, the airbag 2 may include two thickened portions 6. Specifically, the thickened portions 6 are disposed on the inner wall of the main airbag 2.

[0057] A thickened portion 6 is provided on the inner wall of the airbag 2 near the locking part 1. The thickened portion 6 is provided on two side walls adjacent to the connection side of the airbag 2 and the locking part 1.

[0058] Thickened portions 6 are provided on the inner walls of the two sides adjacent to the main airbag 2 near the door body 8. The thickened portions 6 can effectively improve the compression support characteristics of the door seal, thereby improving the service life of the door seal.

[0059] In this embodiment of the present invention, the thickened portion gradually increases in thickness from the end of the housing 7 along the end of the door 8, so as to further improve the stability and support effect of the airbag 2 being compressed.

[0060] Through the above technical solution, the refrigeration equipment and its enclosed door seal structure provided by this utility model are engaged with the door body 8 through the engagement part 1 and the engagement groove 9, so that multiple airbags 2 are squeezed between the door body 8 and the box body 7. At the same time, the strip filling material 4 inside the airbag 2 near the engagement part 1 is also squeezed. Since the strip filling material 4 is fully disposed inside the airbag 2, it can effectively reduce the convection of gas inside the airbag 2, that is, effectively reduce heat conduction and improve the heat preservation effect of the door seal body 3. At the same time, the strip filling material 4 can also support the airbag 2 to maintain the maximum deformation range of the airbag 2, thereby ensuring the reset effect of the airbag 2.
