Description

Technical Field

[0001] The utility model relates to an ice retaining structure, in particular to an ice retaining structure which can be bent and can be placed in different containers according to user requirements. Background Art

[0002] There are two types of refrigerants currently available on the market. One type is mainly composed of high molecular polymers (e.g., cellulose gel), which is not edible and is not environmentally friendly. The other type is composed of water, which is edible and can be reused many times, and is relatively environmentally friendly. Refrigerants are currently commonly used to preserve cakes, popsicles, or fresh food. The method of use is to first place the refrigerant in a freezer to solidify, and then place the refrigerant and the products that need to be kept cold in a box, case, or bag. By absorbing the heat energy in the box or bag, the box or bag can maintain a lower temperature, so that the products that need to be kept cold, such as cakes, popsicles, or fresh food, can prolong their ice preservation time.

[0003] Generally, if you want to keep products cool at room temperature, you usually don't use ice cubes to maintain a low temperature, because the water after the ice cubes melt will accelerate the melting of the ice cubes, and the melted water may also cause damage to the products. Therefore, dry ice or refrigerants are usually used instead. Dry ice will directly vaporize at room temperature without leaving any water, while refrigerants rarely leave any water and can be reused.

[0004] Although the refrigerant can extend the time that the box, case or bag maintains a low temperature, if the product that needs to be kept cold is ice cubes or popsicles, the ice cubes or popsicles may melt but the refrigerant has not thawed. This is because the heat energy in the box, case or bag is not evenly transmitted to the product that needs to be kept cold and the refrigerant in the box, case or bag, so the ice cubes or popsicles melt and thaw before the refrigerant. Utility Model Content

[0005] The technical problem solved by the utility model is as follows: in order to solve the problem that the heat energy in the cold-keeping box or cold-keeping bag cannot be evenly transmitted to the refrigerant and ice cubes or popsicles in the cold-keeping box or cold-keeping bag, causing the ice cubes or popsicles to thaw and melt before the refrigerant, an ice-keeping structure and an ice-keeping container are provided. The ice-keeping structure uses a heat-spreading layer to evenly spread the heat energy so that the heat energy is evenly transmitted to the refrigerant, and then uses an insulating layer to block the heat energy from being transmitted to the ice product, so as to avoid or reduce the situation that the ice product thaws and melts before the refrigerant.

The ice-preserving layer of the first ice-preserving structure is used to absorb heat energy, and the heat-insulating layer of the first ice-preserving structure is used to block the transmission of heat energy, thereby extending the time for the first storage space to maintain a low temperature.

[0015] Optionally, in the above embodiment, the ice-keeping container further includes at least one second ice-keeping structure, which is the ice-keeping structure of the above embodiment, and is used to be arranged at least one of the top and bottom surfaces of the curved / bent structure of the first ice-keeping structure.

[0033] Please refer to Figure 1 , Figure 1 This is an exploded view of the ice retaining structure of the utility model. Figure 1 In the embodiment of the present invention, the ice retention structure is a three-layer structure, which includes a heat spreading layer 1, an ice retention layer 2 and a heat insulating layer 3, wherein the heat spreading layer 1 is arranged on one surface of the ice retention layer 2, and the heat insulating layer 3 is arranged on the other surface of the ice retention layer 2. In other words, the ice retention layer 2 is located between the heat spreading layer 1 and the heat insulating layer 3.

[0034] The heat spreading layer 1 is mainly used to spread the heat evenly, so that the heat energy is evenly spread to the ice preservation layer 2, that is, the heat energy will not be concentrated in one place of the ice preservation layer 2, causing different parts of the ice preservation layer 2 to thaw and melt differently, resulting in poor ice preservation effect. The heat spreading layer 1 uses materials with a thermal conductivity greater than 200W / (m·K), such as aluminum foil, copper foil or graphene, so that the heat spreading energy can spread the heat energy evenly. The ice preservation layer 2 mainly absorbs heat energy, and the ice preservation layer 2 is a refrigerant. By absorbing heat energy, the ice preservation time of the ice preservation structure 100 for products that need to be preserved can be extended. The heat insulation layer 3 is mainly used to block the spread of heat energy, and the heat insulation layer 3 is an insulating material, such as foam, styrofoam or plastic.

[0035] Please refer to Figure 2 , Figure 2 It is a schematic diagram of the connection between the first ice-keeping structure and the second ice-keeping structure. The ice-keeping structure of the present invention is bendable / flexible. The ice-keeping structure 100 can be bent / folded according to the needs of the user, so that the bent / folded ice-keeping structure 100 can conform to the shape of the storage space of containers such as cold-keeping boxes, cold-keeping bags or cold-keeping tubes, and the center of the bent / folded structure will form a first storage space S, and the first storage space S will be exposed to the top and bottom surfaces of the bent / folded structure. When the bent / folded structure is viewed from a top or bottom perspective, the bent / folded structure is polygonal, circular or elliptical, and the shape of the bent / folded structure must match the shape of the storage space of the container. In addition, the ice-keeping structure 100 of the present invention can also be cut into polygonal, circular or elliptical sheets according to the needs of the user. Figure 2 In the embodiment of the present invention, the bending / folding structure of the first ice-keeping structure 100a is cylindrical, and the second ice-keeping structure 100b is a circular sheet. The user can first put the second ice-keeping structure 100b as a base into the ice-keeping container, and then put the first ice-keeping structure 100a into the ice-keeping container. In addition, in the embodiment of the present invention, another second ice-keeping structure 100b can be placed on the top surface of the first ice-keeping structure 100a. Furthermore, the second ice-keeping structure 100b is also bendable / foldable.

[0036] Please refer to Figure 3 , Figure 4 , Figure 3 It is a cross-sectional schematic diagram of placing the ice-preserving structure in the ice-preserving container of the utility model. Figure 4This is an enlarged schematic diagram of the structure of placing the ice-retaining structure in the ice-retaining container of the utility model. Figure 3 In the embodiment of the invention, the ice-keeping container 200 is a container 4 in which the first ice-keeping structure 100a and the second ice-keeping structure 100b are placed in the first accommodation space 41. The first ice-keeping structure 100a is close to the inner wall of the container 4. Then, the product to be kept cold is placed in the first accommodation space S formed by the first ice-keeping structure 100a and the second ice-keeping structure 100b, so that the function of keeping ice can be achieved. Figure 4 As shown, the heat spreading layer 1 in the first ice-keeping structure 100a is adjacent to the inner wall surface of the container 4, and the heat insulating layer 3 of the first ice-keeping structure 100a is adjacent to the product that needs to be kept ice-free. When the user places the product that needs to be kept ice-free in the first accommodating space S of the first ice-keeping structure 100a, the heat energy outside the container 4 is transmitted to the heat spreading layer 1 of the first ice-keeping structure 100a, and then the heat spreading layer 1 of the first ice-keeping structure 100a will evenly spread the heat energy so that the heat energy is evenly transmitted to the ice-keeping layer 2 of the first ice-keeping structure 100a, so that each part of the ice-keeping layer 2 of the first ice-keeping structure 100a can evenly absorb the heat energy, and there will not be only one place that absorbs more heat energy, resulting in a reduced ice-keeping time of the first ice-keeping structure 100a. Then, part of the heat energy will still be transmitted to the insulation layer 3 of the first ice-preserving structure 100a. At this time, the insulation layer 3 of the first ice-preserving structure 100a will block the transmission of heat energy, thereby extending the time for maintaining low temperature in the first accommodating space S of the first ice-preserving structure 100a.

[0037] Supplementary explanation: since the heat spreading layer 1 of the first ice-keeping structure 100a is close to the inner wall of the container 4, and there is a gap between the heat spreading layer 1 of the first ice-keeping structure 100a and the inner wall of the container 4, the gap is not large, but the heat spreading layer 1 and the inner wall of the container 4 will not contact each other, and the heat conduction effect of air is the worst, so the gap between the heat spreading layer 1 and the inner wall of the container 4 also has the effect of extending the ice-keeping time. In addition, the above-mentioned products that need to be kept cold can be ice cubes, popsicles or any other products that need to be kept fresh, and the ice-keeping structure and ice-keeping container of the utility model have a better effect on keeping ice cubes or popsicles.

[0038] In addition, please refer to Figure 5 , Figure 5 This is a cross-sectional schematic diagram of another ice-retaining container of the utility model in which an ice-retaining structure is placed. Figure 3 The container 4 is cylindrical, Figure 5 The container 4 is extended downward at its body, and because the first ice retaining structure 100a is bendable / flexible, its bent / flexed shape corresponds to the shape of the container 4, so that there is the aforementioned small gap between the heat spreading layer 1 and the inner wall of the container 4. In short, the ice retaining structure 100 of the utility model can be used in containers 4 of various shapes, and the utility model is not limited to the shape of the container 4.

[0039] To sum up, the ice-keeping structure and ice-keeping container of the utility model can evenly spread the heat energy through the heat spreading layer, so that the heat energy is evenly transmitted to the ice-keeping layer, so that each part of the ice-keeping layer absorbs the heat energy evenly, and the insulation layer further blocks the propagation of heat energy, so that the products that need to be kept iced can be kept iced for a long time.
