Description

Vacuum beads and methods for producing the vacuum beads

[0001] The present invention relates to a vacuum bead and a method for producing the vacuum bead.

[0002] Insulated containers, or thermos containers, designed to maintain high or low internal temperatures are manufactured with low-thermal-conductivity insulating materials. Furthermore, devices designed to maintain low temperatures, such as refrigerators, also use insulation to prevent heat exchange with the outside world.

[0003] In devices such as insulated containers, thermal containers, and refrigerators, the freezing / refrigeration efficiency can be improved by improving the performance of the insulation material, so higher performance of the insulation material is required.

[0004] Because vacuum has a very high insulating effect, insulated containers are manufactured using vacuum insulation materials (e.g., vacuum insulation panels (VIPs). Vacuum insulation is a type of high-performance insulation that creates a vacuum by depressurizing the internal space, taking advantage of the low thermal conductivity of vacuum.

[0005] VIPs have very low thermal conductivity, as they encase the core with an outer shell and maintain a vacuum inside. For example, the outer shell may be composed of a multilayer polymer and aluminum laminated film to maintain a certain level of vacuum inside the VIP. The core (or core) may be made of glass fiber or silica. The outer shell may be equipped with a getter to absorb gases within the internal space.

[0006] VIP has high initial insulation performance, but it is difficult to maintain a high vacuum for a long period of time, and the vacuum state can be broken due to damage to the outer skin, etc.

[0007] VIP has high insulation performance, but is heavy and expensive to manufacture, so it is used as a container for delivering medicine, but it is difficult to use it as a container for delivering items such as food and fresh produce.

[0008] Insulating materials such as EPS (Expanded Polystyrene), EPP (Expanded Polypropylene), and PIR (Polyisocyanurate) are used as containers for shipping items such as food and fresh produce, but their insulating performance is low.

[0009] The background technology described above is technology that the inventor possessed or acquired in the process of deriving the disclosure of the present application, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the present application.

[0010] The present invention can provide a vacuum bead having a vacuum state inside and a method for manufacturing a vacuum bead.

[0011] According to one embodiment of the present invention, a vacuum bead having superior insulation performance and formability due to lower thermal conductivity compared to existing insulating materials can be provided.

[0045] In addition, when describing with reference to the attached drawings, identical components will be assigned the same reference numerals regardless of the drawing numbers, and redundant descriptions thereof will be omitted.

[0046]

[0047] FIG. 1 and FIG. 2 are drawings showing vacuum beads according to various embodiments.

[0048] Referring to FIG. 1, a vacuum bead according to various embodiments may include a bead body and a bead stopper (105). For example, the bead body may include a first bead body (101-1) and a second bead body (101-2).

[0049] For example, the bead body may include a gap and an internal space. A bead plug (105) may be placed in the gap. The bead plug (105) may be fused to the bead body in a vacuum to seal the gap.

[0050] Fig. 1 shows a state in which the first bead body (101-1), the second bead body (101-2), and the bead stopper (105) are separated. As shown in Fig. 2, the first bead body (101-1) and the second bead body (101-2) can be combined to form a bead body.

[0051] The first bead body (101-1) may include a first gap. The second bead body (101-2) may include a second gap. When the first bead body (101-1) and the second bead body (101-2) are combined, a gap may be formed by the first gap and the second gap. The first gap and the second gap may be formed in the first bead body (101-1) and the second bead body (101-2) to correspond to each other.

[0052] The shape of the first gap and / or the second gap may be semicircular, but is not limited thereto, and the size of the first gap and / or the second gap may be formed in various sizes. In addition, in the following description, an example in which the first gap is formed in the first bead body (101-1) and the second gap is formed in the second bead body (101-2) is described, but the present invention is not limited thereto. For example, the first gap may be formed in the first bead body (101-1) and the second gap may not be formed in the second bead body (101-2).

[0053] The shape and / or size of the gap formed by the first gap and / or the second gap may have various shapes and / or sizes.

[0054] As shown in Fig. 2, the bead plug (105) can be placed in the gap formed by the first gap and the second gap when the first bead body (101-1) and the second bead body (101-2) are combined. The first bead body (101-1) can be combined with the second bead body (101-2). For example, the first bead body (101-1) can be fused with the second bead body (101-2).

[0055] For example, when a bead plug (105) is placed in a gap, the gap of the bead body may not be shielded. As shown in FIG. 2, the body portion of the bead plug (105) may be smaller than the gap. Both ends of the bead plug (105) may be larger than the gap. Since both ends of the bead plug (105) are larger than the gap, the bead body is not shielded, but the bead plug (105) may not come out of the gap.

[0056] The shape and / or size of the bead plug (105) is not limited to the examples shown in FIGS. 1 and 2. For example, the bead plug (105) may be formed in a shape and / or size that does not block the gap when placed in the gap and does not escape from the gap.

[0057] For example, the first bead body (101-1), the second bead body (101-2), and / or the bead cap (105) may include an insulating material. For example, the insulating material may include, but is not limited to, EPS (Expanded Polystyrene), EPP (Expanded Polypropylene), PIR (Polyisocyanurate), LCP (liquid crystal polymer), nanocomposite plastic, etc.

[0058]

[0059] FIG. 3 is a drawing showing a vacuum bead within a vacuum chamber (110) according to various embodiments.

[0060] For example, the bead body (103) and the bead stopper (105) of FIG. 2 may be placed within a vacuum chamber (110). The vacuum chamber (110) may create a vacuum state within the vacuum chamber (110). For example, the vacuum state may refer to an atmospheric state or an atmospheric pressure state formed by the vacuum chamber (110). Since the gap of the bead body (103) is not blocked by the bead stopper (105), the interior of the bead body (103) may be created in a vacuum state by the vacuum chamber (110).

[0061] For example, the bead plug (105) can be fused to the bead body (103) in a vacuum state and block the gap. For example, the bead plug (105) can be fused to the bead body (103) by heat generated in a vacuum state after the first bead body (101-1) and the second bead body (101-2) are combined. The bead plug (105) can expand when it receives heat. The bead plug (105) expands to block the gap and can be fused to the bead body (103). Since the bead plug (105) blocks the gap in a vacuum state, the inside of the bead body (103) can be shielded from the outside in a vacuum state.

[0062] For example, the bead plug (105) may include a material having a melting point different from that of the bead body (103). When the bead plug (105) is heated above the melting point of the bead plug (105), it may be fused to the bead body (103) and block the gap.

[0063] For example, the melting point of the bead body (103) (e.g., the first bead body (101-1), the second bead body (101-2)) may be higher than the melting point of the bead plug (105). For example, the melting point of the bead body (103) may be a first temperature, and the melting point of the bead plug (105) may be a second temperature lower than the first temperature.

[0064] As shown in FIG. 2, when the first bead body (101-1) is fused to the second bead body (101-2), heat may be applied only to the surface where the first bead body (101-1) and the second bead body (101-2) come into contact. Since heat (e.g., heat higher than the first temperature) is applied only to the first bead body (101-1) and the second bead body (101-2) in FIG. 2, the first bead body (101-1) and the second bead body (101-2) may be fused and joined. Since heat is applied only to the first bead body (101-1) and the second bead body (101-2) in FIG. 2, the bead stopper (105) may not be fused to the bead body (103).

[0065] For example, heat may be applied to the inside of the vacuum chamber (110) to be equal to or higher than the second temperature and lower than the first temperature. For example, in FIG. 3, when the temperature inside the vacuum chamber (110) is equal to or higher than the second temperature and lower than the first temperature, the bead plug (105) may expand to seal the gap and be fused to the bead body (103).

[0066] For example, the bead plug (105) may include a porous material that absorbs moisture. The bead plug (105) may be fused to the bead body (103) by heat generated when microwaves are applied within a vacuum chamber (110) and may block the gap.

[0067] For example, a catalyst may be applied to the surface of the bead plug (105). When the catalyst reacts with a substance that reacts with the catalyst, heat may be generated. The bead plug (105) may be fused to the bead body (103) and may block the gap due to the heat generated when the catalyst reacts with the substance that reacts with the catalyst.

[0068] For example, a UV (ultraviolet) adhesive may be applied to the surface of the bead plug (105). When UV is irradiated onto the surface of the bead plug (105), the bead plug (105) is fused to the bead body (103) and can block the gap.

[0069] In the above example, the bead plug (105) may adsorb water before being placed in the gap, or a catalyst or UV adhesive may be applied to the surface.

[0070] For the sake of convenience of understanding, FIG. 3 illustrates an example in which a single bead body (103) and a bead stopper (105) coupled to the bead body (103) are positioned in a vacuum chamber (110), but is not limited thereto. For example, a plurality of bead bodies and bead stoppers coupled to the plurality of bead bodies illustrated in FIG. 6 below may be positioned in a vacuum chamber (110).

[0071] When the bead body (103) is positioned within the vacuum chamber (110), the internal space of the bead body (103) can be in a vacuum state because the diameter of the gap is larger than the diameter of the body part of the bead plug (105).

[0072] For example, the bead plug (105) may include a through hole. For example, the through hole may be formed longitudinally in the center of the bead plug (105). For example, the through hole may be formed to connect the exterior of the bead body and the interior space of the bead body (103). Through the through hole of the bead plug (105), fluid flow between the interior space of the bead body (103) and the exterior of the bead body may be possible. In a vacuum chamber (110), even if the interior space of the bead body (103) is sealed by the bead plug (105) due to pressure, the interior space of the bead body (103) may be in a vacuum state through the through hole.

[0073] When heat is applied to the bead plug (105) within the vacuum chamber (110), the through hole can be shielded. For example, since the bead plug (105) expands due to heat, the through hole can be shielded.

[0074] For example, both ends of the bead plug (105) may be formed in a shape that prevents the gap from being separated and does not block the gap. For example, both ends of the bead plug (105) may be formed in a cross shape. The size and / or length of the cross shape may be larger than the size of the gap. Even if the bead plug (105) placed in the gap is forced in one direction by pressure, the bead plug (105) may not block the gap.

[0075] For example, the body portion of the bead plug (105) can be formed in a shape corresponding to the shape of the gap.

[0076]

[0077] FIG. 4 is a drawing showing a vacuum bead (100) according to various embodiments.

[0078] When a bead plug (105) is fused to a bead body in the vacuum chamber (110) of FIG. 3, a vacuum bead (100) having a vacuum state inside can be created, as shown in FIG. 4. The bead plug (105) of FIG. 3 can be fused to form a fused bead plug (107) as shown in FIG. 4. Since the bead plug (107) is fused in a vacuum state and blocks the gap of the bead body, the inside of the bead body is in a vacuum state.

[0079] As described in the above-described drawings 1 to 4, a vacuum bead (100) can be manufactured. For example, a method for manufacturing a vacuum bead (100) may include an operation of forming a bead body including a gap by combining a first bead body (101-1) in which a first gap is formed and a second bead body (101-2) in which a second gap is formed. For example, the bead body may be formed in a state in which a bead stopper (105) is placed in the gap formed by the first gap and the second gap.

[0080] For example, a method for manufacturing a vacuum bead (100) may include an operation of fusing a bead plug (105) to a bead body in a vacuum state to block a gap. For example, the bead body and the bead plug (105) positioned in the gap may be placed inside a vacuum chamber (110). In a vacuum state, the bead plug (105) may be fused to the bead body and block the gap.

[0081] For example, by controlling the temperature inside the vacuum chamber (110) to a temperature higher than the melting point of the bead plug (105), the bead plug (105) can be fused to the bead body and the gap can be sealed.

[0082] For example, the bead plug (105) may include a porous material that absorbs water. When microwaves are irradiated in a vacuum, the bead plug (105) can be fused to the bead body by the generated heat and block the gap.

[0083] For example, a catalyst may be applied to the surface of the bead plug (105). When the catalyst reacts with a substance that reacts with the catalyst, the bead plug (105) may be fused to the bead body by the generated heat and may block the gap.

[0084] For example, a UV adhesive may be applied to the surface of the bead plug (105). When UV is irradiated to the bead plug (105), the bead plug (105) can be fused to the bead body and block the gap.

[0085] When manufacturing containers, insulators, etc. with a vacuum inside, the internal state can be created by first creating a vacuum and then fusing the parts that allow airflow. However, when fusing the parts that allow airflow, the gases generated can enter the container, insulator, etc. interior. These gases can interfere with maintaining the vacuum.

[0086] In the case of the vacuum bead (100) according to one embodiment, the area and / or range in which the bead plug (107) is fused is small. Since the range in which the bead plug (107) is fused is localized, the amount of gas flowing into the vacuum bead (100) may be small. Since the amount of gas flowing into the vacuum bead (100) is small, the vacuum bead (100) can maintain the interior in a vacuum state for a long period of time.

[0087] Referring to FIGS. 3 and 4, a vacuum bead (100) according to various embodiments can be manufactured only by heat applied to a bead plug (105) in a vacuum state. In a vacuum state, a mechanical force may be applied to the bead body (103) (e.g., the first bead body (101-1), the second bead body (101-2)) and / or the bead plug (105), or the vacuum bead (100) may be formed in a fixed state that does not move.

[0088] For example, the interior of the bead body may be filled with aerogel. Aerogel is a solid material, and refers to a material filled with gas instead of liquid in a gel.

[0089]

[0090] FIGS. 5 and 6 are drawings showing a method of manufacturing a plurality of vacuum beads (e.g., vacuum beads (100) of FIG. 4) according to various embodiments.

[0091] Referring to FIG. 5, a method for manufacturing a plurality of vacuum beads according to one embodiment may include an operation of aligning a plurality of first bead bodies (120) coupled to a first guide member, a plurality of second bead bodies (130) coupled to a second guide member, and a plurality of bead plugs (140) coupled to a third guide member.

[0092] For example, the first guide member, the second guide member, and the third guide member are members for assisting the combination of a plurality of first bead bodies (120), a plurality of second bead bodies (130), and a plurality of bead stoppers (140). For example, by aligning the first guide member, the second guide member, and the third guide member, as shown in FIG. 6, each of the plurality of first bead bodies (120), the plurality of second bead bodies (130), and the plurality of bead stoppers (140) can be aligned at positions for producing a plurality of vacuum beads.

[0093] For example, a plurality of first bead bodies (120) and a plurality of second bead bodies (130) may be combined to form a plurality of bead bodies. Each of the plurality of first bead bodies (120) may include a first gap. Each of the plurality of second bead bodies (130) may include a second gap. Each of the plurality of bead bodies may include a gap formed by the first gap and / or the second gap. As shown in FIG. 6, when the plurality of first bead bodies (120), the plurality of second bead bodies (130), and the plurality of bead plugs (140) are aligned, the plurality of bead plugs (140) may be positioned in their respective gaps.

[0094]

[0095] FIG. 6 is a drawing showing a plurality of first bead bodies (120), a plurality of second bead bodies (130), and a plurality of bead plugs (140) aligned according to a guide member.

[0096] FIG. 6 shows a state (150) in which a plurality of first bead bodies (120), a plurality of second bead bodies (130), and a plurality of bead plugs (140) are combined to form a plurality of bead bodies.

[0097] Referring to FIG. 6, a method for manufacturing a plurality of vacuum beads according to an embodiment may include an operation of generating a plurality of bead bodies by combining second bead bodies (101-2) corresponding to each of a plurality of first bead bodies (120). For example, in FIG. 6, heat may be applied only to the plurality of first bead bodies (120) and the plurality of second bead bodies (130) to form the plurality of bead bodies. When the plurality of bead bodies are formed, heat may not be applied to each of the plurality of bead plugs (140). When the plurality of bead bodies are formed, gaps between the plurality of bead bodies may not be sealed.

[0098] For example, a method for manufacturing a plurality of vacuum beads may include an operation of fusing a plurality of bead plugs (140) to each of a plurality of bead bodies in a vacuum state. For example, a plurality of bead bodies and a plurality of bead plugs (140) may be positioned within a vacuum chamber (110).

[0099] For example, by controlling the temperature within the vacuum chamber (110) to a temperature higher than the melting point of the plurality of bead plugs (140), the plurality of bead plugs (140) can be fused to each of the plurality of bead bodies. For example, the melting point of the plurality of bead plugs (140) can be lower than the melting point of the plurality of first bead bodies (120) and / or the plurality of second bead bodies (130). When the plurality of bead plugs (140) are fused to the plurality of bead bodies, the plurality of bead plugs (140) can shield the gaps between each of the plurality of bead bodies.

[0100] For example, the plurality of bead plugs (140) may include a porous material that absorbs water. When microwaves are irradiated in a vacuum, the plurality of bead plugs (140) may be fused to each of the plurality of bead bodies by the generated heat. When the plurality of bead plugs (140) are fused to the plurality of bead bodies, they may shield the gaps between each of the plurality of bead bodies.

[0101] For example, a catalyst may be applied to the surfaces of a plurality of bead plugs (140). When the catalyst reacts with a substance that reacts with the catalyst in a vacuum, the plurality of bead plugs (140) may be fused to each of the plurality of bead bodies by the heat generated. When the plurality of bead plugs (140) are fused to the plurality of bead bodies, they may block the gaps between each of the plurality of bead bodies.

[0102] For example, a UV adhesive may be applied to the surfaces of a plurality of bead plugs (140). When UV is irradiated in a vacuum, the plurality of bead plugs (140) may be fused to each of the plurality of bead bodies. When the plurality of bead plugs (140) are fused to the plurality of bead bodies, they may block the gaps between each of the plurality of bead bodies.

[0103] Referring to FIGS. 5 and 6, a plurality of vacuum beads according to one embodiment can be produced within a single vacuum chamber. Conventional vacuum insulation materials (e.g., vacuum insulation panels (VIPs)) are each produced in a vacuum state. A plurality of vacuum beads according to one embodiment can be produced simultaneously in a vacuum state.

[0104]

[0105] An insulating material can be manufactured using the vacuum beads (100) illustrated in FIGS. 1 to 6 above or vacuum beads (100) manufactured according to the manufacturing method. For example, a plurality of vacuum beads (100) can be placed in a predetermined mold and heat applied to manufacture an insulating material. The method of manufacturing an insulating material using a plurality of vacuum beads (100) can be applied in substantially the same manner as the method of manufacturing an insulating material using known insulating materials.

[0106]

[0107] FIGS. 7 and 8 are drawings illustrating an insulating material including multiple layers according to various embodiments.

[0108] Referring to FIGS. 7 and 8, the insulation according to various embodiments may include a first layer (205, 209) formed of a plurality of vacuum beads (e.g., vacuum beads (100) of FIG. 4) and a second layer (201, 203, 207) formed of a plurality of insulating members.

[0109] In FIGS. 7 and 8, the insulation including a plurality of layers may include a second layer (201, 203, 207) including a plurality of insulating members. For example, the plurality of insulating members may represent known insulating beads. For example, the second layer (201, 203, 207) may include insulating members such as Expanded Polystyrene (EPS), Expanded Polypropylene (EPP), Polyisocyanurate (PIR), Liquid Crystal Polymer (LCP), Nano Composite Plastic, etc.

[0110] In FIGS. 7 and 8, the first layer (205, 209) may include a vacuum bead according to various embodiments, a vacuum bead manufactured according to a method for manufacturing a vacuum bead, or a vacuum bead manufactured according to a method for manufacturing a plurality of vacuum beads.

[0111] Fig. 7 is a drawing illustrating an insulating material comprising multiple layers manufactured using mesh partitions.
