Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vacuum containers, in particular to a vacuum layer supporting structure of a non-circular container. Background Art
[0002] Common vacuum containers include insulated lunch boxes, portable insulated refrigerators, and vacuum insulated pots. In order to disperse the pressure exerted by atmospheric pressure on the outer and inner liner surfaces, the existing vacuum insulation layer adopts a circular or nearly circular structure (such as a cylinder or a cone that is narrow at the top and wide at the bottom). Although the circular cross-section design can make the structure stable, it obviously limits the design of the shape of the vacuum container. For example, most portable insulated refrigerators currently use a square design, which adds insulation materials to prevent cooling leakage, and are not equipped with a vacuum insulation layer. If these refrigerators are equipped with a vacuum insulation layer, the internal space needs to adopt a cylindrical design. Under the condition of the same diameter, the volume of the cylinder is smaller than that of the cuboid, that is, the deformation reduces the storage space. At the same time, the curved side wall design is not convenient for placing food and drinks.
[0003] For another example, a relatively large cylindrical thermos is not easy to hold with one hand. When the side wall of the thermos has at least one plane, the degree of stretching of the palm can be reduced to facilitate holding. However, when the side wall of the container has at least one plane, there is a lack of supporting structure between the inner liner and the outer liner. Therefore, when vacuuming, the plane of the side wall of the outer liner will collapse toward the inner liner. Even if the status quo can be maintained without collapse, when holding the container, the fingers will apply pressure to the plane, which can easily cause deformation of the plane. Moreover, when the plane is impacted by external force, it is more likely to produce irreversible deformation than the circular one, resulting in the local inner wall space being too narrow and the vacuum insulation effect being reduced.
[0004] The above defects are the reason why non-circular thermal insulation containers are rarely seen on the market. Previously, the company filed a patent application with number 202322249158X, named a non-circular vacuum container with internal support, to solve the above problems. Now another solution that can solve the above technical problems is proposed. Summary of the invention
[0005] The purpose of the utility model is to provide a vacuum layer support structure for a non-circular container to solve the problems raised in the above background technology.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A non-circular container vacuum layer support structure comprises an inner liner and a cylindrical outer liner with a non-circular cross section, wherein the outer liner is sleeved on the outer periphery of the inner liner to form a vacuum layer therebetween, and a support frame with low thermal conductivity is arranged in the vacuum layer, and the support frame abuts against the inner side of the outer liner and the outer side of the inner liner.
[0008] According to a further technical solution, both the outer side of the inner liner and the inner side of the outer liner are coated with a graphene heat insulation layer.
[0009] According to a further technical solution, the support frame includes a support plate 1 abutting against the inner side of the outer liner and a support plate 2 abutting against the outer side of the inner liner, and the support plate 1 and the support plate 2 are provided with a plurality of small-area support members, and one end of the support member is in point contact with the support plate 1 or the support plate 2.

[0018] Beneficial effects of the utility model:

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0030] Please refer to Figure 1-7 ;
[0031] The container described in the utility model is a non-circular structure, which has a vacuum layer 3 for isolating the transfer of heat. By arranging a support structure in the vacuum layer 3, a support force can be provided to the outer liner 2 to prevent it from collapsing and deforming inward when subjected to external force or vacuuming; it specifically includes an inner liner 1 and an outer liner 2 with a non-circular cross section. It should be noted that "non-circular cross section" can have three interpretations, the first is "non-circular, columnar", such as a prism or other columnar shape, the second is "non-circular, non-columnar", such as a bent structure; the third is "circular, non-columnar", such as a bent shape based on a cylinder; the outer liner 2 is sleeved on the outer periphery of the inner liner 1 to form a vacuum layer 3 between the two, and the vacuum layer 3 is provided with a support skeleton 4 with low thermal conductivity in the vacuum layer 3, and the support skeleton 4 abuts against the inner side of the outer liner 2 and the outer side of the inner liner 1;
[0032] It should be noted that the support frame 4 should have a hollow gap to ensure that the vacuum layer 3 still exists.
[0033] In this embodiment, a flat vacuum container is used for illustration. First, the inner liner 1, the outer liner 2 and the support frame 4 are made separately. When assembling, the support frame 4 is first placed in the inner cavity of the outer liner 2. The support frame 4 has two or four sides, or four sides, which are respectively close to the outer liner 2. Then, the inner liner 1 is placed in the inner cavity of the outer liner 2 by a forced plugging method. After completion, the two sides of each support frame 4 are respectively close to the inner side of the outer liner 2 and the outer side of the inner liner 1. At the same time, the support frame 4 is squeezed and fixed by the inner liner 1 and the outer liner 2. When the installation is completed, the distance between the inner liner 1 and the outer liner 2 bracket should be greater than or equal to 3 mm. Due to the vacuum method, In actual circumstances, the vacuum is not in an ideal state, and air will still be retained. According to research, if the spacing of the vacuum layer 3 is less than 3mm, the residual air can be used to transfer heat through thermal radiation, and the heat in the inner liner 1 will be transferred to the outer liner 2 through thermal radiation, that is, when the space of the vacuum layer 3 is less than 3mm, the thermal insulation effect will fail. Of course, the spacing distance of the vacuum layer 3 will vary depending on the materials used for the inner liner 1 and the outer liner 2. Only data under normal circumstances are listed here, and it should not be used as a limitation on the scope of protection; finally, the openings of the inner liner 1 and the outer liner 2 can be sealed by welding or the like, and of course, exhaust holes will be reserved for vacuuming.
[0034] Since the vacuuming adopts the baking method, the container needs to be placed in an oven at 500 degrees Celsius, so the support frame 4 needs to be made of high-strength high-temperature resistant materials, such as aluminum-stainless steel-titanium, etc. Since metal materials have good thermal conductivity, the solution adopted in this application is to reduce the contact area as much as possible while achieving the support effect, so as to achieve the purpose of reducing heat transfer.
[0035] After the container is cooled, the inner liner 1 and the outer liner 2 are squeezed by the atmosphere and tend to collapse toward the vacuum layer 3. The support frame 4 can withstand the pressure from the inner liner 1 to the outside and the pressure from the outer liner 2 to the inside while maintaining the shape. In particular, for containers with flat side walls, the stability of the structure is enhanced by the support frame 4. In addition to maintaining the shape, it can also prevent the vacuum layer 3 structure from being damaged by concave due to a large impact force. This characteristic can also be used to break the inherent cylindrical design, making it more diversified. By reducing the contact area, the heat transfer is reduced as much as possible, and the factors affecting the thermal insulation are minimized.
[0036] One embodiment of the support frame 4 of the present invention is shown in FIG. Figure 2The support frame 4 includes a support plate 1 41 abutting against the inner side of the outer liner 2 and a support plate 2 42 abutting against the outer side of the inner liner 1. Assuming that the inner liner 1 and the outer liner 2 have a planar structure, the support plate 1 41 and the support plate 2 42 are straight plates. If the inner liner 1 and the outer liner 2 have curved surfaces, the support plate 1 41 and the support plate 2 42 are both curved plates. The ultimate purpose is to abut against the inner side of the outer liner 2 and the outer side of the inner liner 1 respectively. The support plate 1 41 and the support plate 2 42 are provided with a plurality of small-area support members. 43, one end of the support member 43 abuts against the support plate 1 41 or the support plate 2 42, that is, the support member 43 can be set on the support plate 1 41, and the other end abuts against the support plate 2 42, or the support frame is fixed on the support plate 2 42, and the other end abuts against the support plate 1 41. No matter which method is adopted, the abutting end of the support member 43 must be a small area, basically achieving point contact with the support plate 1 41 or the support plate 2 42, thereby reducing the contact area and reducing heat transfer.
[0037] Support plate 1 41 and support plate 2 42 can be a whole plate, covering the plane of the inner liner 1 or the outer liner 2, or support plate 1 41 and support plate 2 42 can be composed of a plurality of plates, which are arranged at intervals, wherein the distribution of support plate 1 41 and support plate 2 42 can be longitudinally or transversely, which is not limited here. When the latter method is adopted, before inserting the inner liner 1, the relative position of support plate 1 41 and support plate 2 42 can be fixed with the help of external tools, and then the inner liner 1 can be forced in, and finally the external tools can be removed.
[0038] The first embodiment of the support member 43 of the utility model refers to Figure 3 , wherein the support member 43 is a support beam 431, the length of the support beam 431 is greater than or equal to 3 mm, and the diameter is less than or equal to 1 mm. Since the support beam 431 is very small, the supporting force of a single beam is limited, but by vertically arranging multiple beams with the support plate 1 41 and the support plate 2 42 respectively, the supporting effect can also be achieved. Because the support beam 431 is very small, the point contact effect can basically be achieved.
[0039] When the inner tank 1 is filled with hot water, the heat of the inner tank 1 will be transferred to the support plate 2 42. Since the support beam 431 and the support plate 2 42 or the support plate 1 41 are in point contact, very little heat will be transferred to the support plate 1 41 or the support plate 2 42 through the support beam 431. Even if a plurality of support beams 431 are provided, the added area thereof is very small, and the transferred heat is also very limited. At the same time, a vacuum layer 3 is provided, and the inner tank 1 will not be transferred to the outer tank 2 by heat radiation, so most of the heat can be isolated, thereby achieving a heat preservation effect.
[0040] Furthermore, one end of the support beam 431 is connected to a conical base 432. Figure 3Assuming that the support plate 41 is a fixed side, the support beam 431 is connected to the support plate through a conical base 432. Since the support beam 431 is very small, the heat transferred will be very concentrated, so a conical base 432 is set to disperse the heat transferred to the support plate 41.
[0041] Preferably, refer to Figure 4 A plurality of support beams 431 are provided on each of the support plates 1 41 and 2 42, and the support beams 431 on both sides are staggered. Assuming that three support beams 431 are provided on each of the support plates 1 41 and 2 42, the support plate 2 42 can be placed in reverse during installation so that the support beams 431 on the support plate 1 41 and the support beams 431 on the support plate 2 42 are staggered and conflict with each other, so that production can be carried out using a set of molds.
[0042] The second embodiment of the support member 43 of the present invention is shown in FIG. Figure 5 The difference between this embodiment and the first embodiment is that the support member 43 adopts a conical protrusion 433, which may be a cone, a truncated cone with a very small top area, a triangle, a prism with a very small top area, etc. Since the end point of the conical protrusion 433 is very small, it can achieve point contact with the support plate 1 41 or the support plate 2 42, and the structure using the conical protrusion 433 is easier to produce, has a better supporting effect, and the number of support members 43 is smaller. The specific effect is the same as the first example.
[0043] Regarding one embodiment of the conical conical protrusion 433, refer to Figure 6 , a plurality of conical convex points 433 are provided on each of the support plate 1 41 and the support plate 2 42, the conical convex points 433 on both sides are staggered with each other, and the height of the conical convex points 433 is greater than or equal to 3 mm; another embodiment is, referring to Figure 7 A plurality of conical protrusions 433 are provided on each of the support plates 1 41 and 2 42 , and the conical protrusions 433 on both sides correspond to each other one by one, that is, the ends of the conical protrusions 433 on the support plates 1 41 and 2 42 are abutted, and the height of the two conical protrusions 433 after abutting is greater than or equal to 3 mm.
[0044] It should be noted that the cone-shaped protrusions 433 also have the effect of dispersing heat.
[0045] In the embodiment of the utility model, the side wall of the outer liner 2 is provided with a plurality of grooves 5 extending inwardly. The grooves 5 formed on the outside can serve as anti-slip grooves to facilitate users to pick up, and the convex edges formed on the inside are intended to reduce the contact area between the support plate 41 and the inner side of the outer liner 2.
[0046] Based on all the embodiments of the utility model, before assembly, a graphene heat insulation layer is coated on the outer side of the inner liner 1 and the inner side of the outer liner 2 to further reduce heat transfer.
[0047] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
[0048] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementations that can be understood by those skilled in the art.
