[0042] Refrigerators have become a widely used household appliance. Door seals play an important role in the heat preservation and insulation of refrigerators.

[0043] In the related art, the door seal of existing refrigerators usually adopts a polyvinyl chloride (PVC) extruded airbag structure, and the PVC material has a high thermal conductivity, which leads to large fluctuations in the energy consumption of the whole machine.

[0044] Based on the above problems, the utility model proposes a door seal with low thermal conductivity to save energy consumption of the whole machine. The door seal can be used in various industries such as automobiles, doors and windows, cabinets, refrigerators, containers, etc.

[0045] See also Figure 1 In one embodiment of the present invention, the door seal 10 includes a waterproof skin layer 11 and a heat-insulating core layer 12; the heat-insulating core layer 12 is filled in the waterproof skin layer 11, and the heat-insulating core layer 12 is a fiber material layer.

[0046] The technical solution of the utility model is to fill a thermal insulation core layer 12 in a waterproof skin layer 11 to form a door seal 10, wherein the thermal insulation core layer 12 is a fiber material layer. Since the fiber material layer has excellent resilience and compensation properties, it has better sealing and heat preservation functions, so that the thermal conductivity of the door seal 10 is low, which can effectively save the energy consumption of the whole machine.

[0047] In addition, the design of the waterproof skin layer 11 can effectively block the contact between water vapor and the thermal insulation core layer 12, and can inhibit the reduction of the sealing and thermal insulation functions of the thermal insulation core layer 12 due to water absorption and freezing. It has high stability, is non-sticky after long-term use, has no odor, and is scratch-resistant. Moreover, the fiber material layer has good low-temperature resistance, which can usually reach -40 to -50°C, which can solve the problem of low-temperature embrittlement of PVC.

[0048] As some examples, the waterproof skin layer 11 and the thermal insulation core layer 12 can adopt a continuous co-extrusion composite process to form a new door seal 10 with a skin-core composite structure. This can make the bonding stability of the waterproof skin layer 11 and the thermal insulation core layer 12 higher, and there will be no problem of separation from each other to affect the service life of the door seal 10.

[0049] In actual application, the material of the waterproof skin layer 11 can be plastic, rubber, fiber or other waterproof materials, as long as it can effectively prevent water vapor from contacting the thermal insulation core layer 12 .

[0050] In actual application, the heat-insulating core layer 12 may fill the entire space in the waterproof skin layer 11 , or may only fill a portion of the space in the waterproof skin layer 11 .

[0051] Furthermore, in actual application, the thickness of the thermal insulation core layer 12 at various positions may be equal or unequal; similarly, the thickness of the waterproof coating at various positions may be equal or unequal.

[0052] It should be noted that the cross-sectional shape of the door seal 10 includes but is not limited to: Figure 1 The rectangle shown may also be a trapezoid, a circle, a semicircle, an ellipse, a semi-ellipse, a pentagon, a hexagon, etc. The specific shape may be determined according to actual usage and is not specifically limited here.

[0053] In actual application, the door seal 10 is not limited to four sides joined together by welding. For example, the four sides of the door seal 10 may also be an integrally formed structure to form a loop.

[0054] See also Figure 1 In one embodiment of the utility model, the fiber material layer is one or more of natural fiber, polyester and copolyester fiber, viscose fiber, acetate fiber, polyacrylonitrile fiber, polypropylene (PP, Polypropylene) fiber, polyurethane (PU, polyurethane) fiber, aramid fiber, and asbestos fiber.

[0055] In this way, by selecting one or more of natural fibers, polyester and copolyester fibers, viscose fibers, acetate fibers, polyacrylonitrile fibers, polypropylene fibers, polyurethane fibers, aramid fibers, and asbestos fibers as the fiber material layer, the thermal insulation core layer 12 can have more excellent resilience and compensation properties, so as to achieve better sealing and thermal insulation properties.

[0056] In actual application, natural fibers can be plant fibers, such as cotton, linen, etc.; natural fibers can also be animal fibers, such as wool, rabbit hair, silk, etc.

[0057] It should be noted that when the fiber material layer is a plurality of natural fibers, polyester and copolyester fibers, viscose fibers, acetate fibers, polyacrylonitrile fibers, polypropylene fibers, polyurethane fibers, aramid fibers, and asbestos fibers, the plurality of materials can be stacked or spliced ​​to form a fiber material layer, or the fiber material layer formed by the plurality of materials is an existing common material layer.

[0058] See also Figure 1 In one embodiment of the utility model, the natural fiber is one or more of cotton, linen, and wool. In this way, when the fiber material layer is natural fiber, by selecting one or more of cotton, linen, and wool as the fiber material layer, not only can the thermal insulation core layer 12 have better resilience and compensation, so as to achieve better sealing and thermal insulation performance, but also the cost of cotton, linen, and wool is lower than that of silk.

[0059] It should be noted that when the natural fiber is a plurality of types of cotton, linen, and wool, the plurality of materials may be stacked or spliced ​​to form the natural fiber, or the natural fiber formed by the plurality of materials may be an existing common natural fiber.

[0060] See also Figure 1In one embodiment of the utility model, the polyester and copolyester fibers are one or more of polyethylene terephthalate (PET) fibers, polybutylene terephthalate (PBT) fibers, polytrimethylene terephthalate (PTT) fibers, poly1,4-cyclohexylenedimethylene terephthalate (PCT) fibers, polyethylenenaphthalate two formic acid glycol ester (PEN) fibers, and polyethylene terephthalate glycol-1,4-cyclohexane dimethanol ester (PETG) fibers.

[0061] In this way, when the fiber material layer is polyester and copolyester fiber, by selecting one or more of polyethylene terephthalate fiber, polybutylene terephthalate fiber, poly(propylene terephthalate)-1,3-diol fiber, polyethylene terephthalate 1,4-cyclohexanedimethylene terephthalate fiber, polyethylene naphthalate fiber, and polyethylene terephthalate-1,4-cyclohexanedimethanol ester fiber as the fiber material layer, the thermal insulation core layer 12 can have more excellent resilience and compensation properties, so as to achieve better sealing and thermal insulation performance.

[0062] It should be noted that when the polyester and copolyester fibers are multiple types of PET fibers, PBT fibers, PT fibers, PCT fibers, PEN fibers, and PETG fibers, the multiple materials can be stacked or spliced ​​to form polyester and copolyester fibers, or the polyester and copolyester fibers formed by the multiple materials are the existing common structures.

[0063] See also Figure 1 In one embodiment of the present invention, the fiber material layer is fine denier fiber; it should be noted that fine denier fiber refers to a fiber having a fineness classification of 1.0 dpf to 2.4 dpf.

[0064] In this way, by designing a fine-denier process for the fiber material, fine-denier fibers are used as the fiber material layer, which can make the resilience and compensation of the thermal insulation core layer 12 better, and can further improve the thermal insulation performance of the thermal insulation core layer 12.

[0065] See also Figure 1 In one embodiment of the utility model, the fiber material layer is elastic fiber; it should be noted that elastic fiber refers to a fiber material that is formed by "false twisting" to produce a certain curvature, and the false twist is opened to produce elongation after being subjected to external force, and the false twist is restored after the external force is removed, so that the fiber has a certain resilience.

[0066] In this way, by designing a texturizing process for the fiber material and using texturized fibers as the fiber material layer, the resilience and compensation of the thermal insulation core layer 12 can also be improved, so as to further improve the thermal insulation performance of the thermal insulation core layer 12 .

[0067] See also Figure 1 In one embodiment of the utility model, the fiber material layer is a hollow fiber; it should be noted that the hollow fiber refers to a chemical fiber with a tubular cavity in the axial direction of the fiber material, that is, a chemical fiber with a tubular cavity running through the axial direction of the fiber. The hollow fiber contains a large amount of static air, which can bring light elasticity, good moisture permeability and comfortable thermal insulation effect to the product.

[0068] In this way, by designing a hollow process for the fiber material, hollow fibers are used as the fiber material layer, which can also improve the resilience and compensation of the thermal insulation core layer 12 to further improve the thermal insulation performance of the thermal insulation core layer 12.

[0069] As some exemplary embodiments, the fiber material layer can be simultaneously refined, elasticized and hollowed out, which can better improve the resilience and compensation of the thermal insulation core layer 12 and effectively improve the thermal insulation performance of the thermal insulation core layer 12.

[0070] See also Figure 1 In one embodiment of the present invention, the waterproof skin layer 11 is a plastic part.

[0071] In this way, by making the material of the waterproof skin layer 11 plastic, not only can the waterproof skin layer 11 effectively block the contact between water vapor and the thermal insulation core layer 12, so as to inhibit the functional degradation of the thermal insulation core layer 12 caused by water absorption and freezing, but also the strength of the waterproof skin layer 11 can be higher to have strong scratch resistance. In this way, not only the aesthetics of the waterproof skin layer 11 can be ensured, but also the waterproof skin layer 11 can be prevented from being scratched to affect the waterproof effect of the thermal insulation core layer 12.

[0072] In practical applications, the material of the waterproof skin layer 11 can be thermoplastic plastic or thermosetting plastic.

[0073] See also Figure 1In one embodiment of the utility model, the waterproof cortex 11 includes one or more of polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic polyester elastomer (TPEE), polyurethane elastomer (TPU), and nylon elastomer (TPAE).

[0074] In this way, by selecting one or more of polyvinyl chloride, thermoplastic elastomer, thermoplastic polyester elastomer, polyurethane elastomer, and nylon elastomer as the material of the waterproof skin layer 11, the waterproof skin layer 11 can have better waterproofness and scratch resistance, and can better block the contact between water vapor and the thermal insulation core layer 12, so as to inhibit the functionality of the thermal insulation core layer 12 from being reduced due to water absorption and freezing.

[0075] It should be noted that when the waterproof skin layer 11 includes multiple materials of PVC, TPE, TPEE, TPU, and TPAE, the multiple materials can be stacked or spliced ​​to form the waterproof skin layer 11, or the waterproof skin layer 11 formed by multiple materials is an existing common structure.

[0076] See also Figure 1 In one embodiment of the utility model, one or at least two cavities 111 are formed in the waterproof skin layer 11 , and at least one cavity 111 is filled with a thermal insulation core layer 12 .

[0077] With such arrangement, when a cavity 111 is formed in the waterproof skin layer 11, the cavity 111 can be completely filled with the thermal insulation core layer 12, or a partial area in the cavity 111 can be filled with the thermal insulation core layer 12, and the partial area in the cavity 111 is in a hollow state; when at least two cavities 111 are formed in the waterproof skin layer 11, one of the cavities 111 can be filled with the thermal insulation core layer 12, and the other cavity 111 is in a hollow state; in this way, the hollow area inside the waterproof skin layer 11 can be size-compensated, so that the waterproof skin layer 11 also has excellent resilience and compensation, so that the door seal 10 has better sealing performance.

[0078] In actual application, when at least two cavities 111 are formed in the waterproof leather layer 11, the shapes and sizes of the at least two cavities 111 may be the same or different, and the at least two cavities 111 may be spaced apart along the length direction of the waterproof leather layer 11, or may be spaced apart along the width direction of the waterproof leather layer 11, or may be spaced apart along the thickness direction of the waterproof leather layer 11.

[0079] See also Figure 1 In one embodiment of the present invention, the door seal 10 does not contain a magnetic stripe capsule. That is, the cavity 111 of the waterproof skin layer 11 of the door seal 10 does not contain a magnetic stripe capsule, and the cavity 111 of the waterproof skin layer 11 is used to fill the heat preservation core layer 12 or to make a hollow design.

[0080] With such arrangement, there is no need to arrange a magnetic strip bag in the door seal 10 , which can simplify the structural design of the door seal 10 .

[0081] See also Figure 3 In one embodiment of the present utility model, the waterproof leather layer 11 is provided with a connecting structure, and the connecting structure is used to be connected to the door body 20.

[0082] With such an arrangement, the method of setting a magnetic strip structure inside the door seal 10 is eliminated. By setting a connecting structure in the waterproof leather layer 11 and connecting it to the door body 20, it is easier to form a connecting structure that is connected to the door body 20.

[0083] In actual application, the connection structure can specifically be a snap-fit ​​structure 13 , glue, a hook or the like, as long as the connection structure is connected to the door body 20 .

[0084] As some exemplary embodiments, the connection structure can be integrally formed with the waterproof skin layer 11, which can not only ensure the connection strength between the connection structure and the waterproof skin layer 11, but also simplify the preparation process.

[0085] See also Figure 3 In one embodiment of the present invention, the connection structure is a snap-fit ​​structure 13 , and the snap-fit ​​structure 13 is used to cooperate with the slot 21 of the door body 20 .

[0086] With such a configuration, when installing the door seal 10, the buckle structure 13 on the door seal 10 is directly snapped into the slot 21 of the door body 20 to achieve the installation of the door seal 10.
