[0001] This application relates to the field of vacuum insulation panel technology, and more specifically to a modular vacuum insulation panel. Background Technology

[0002] Currently, insulation materials represented by polyurethane foam are no longer sufficient to meet the technical requirements of diversified applications in home appliances, construction, and other fields. New thermal insulation materials and technologies have emerged as a result. Vacuum insulation panels, as a type of thermal insulation board, have a lower thermal conductivity than traditional insulation materials, making them more suitable for applications requiring high efficiency, energy saving, and lightweight structures. They have been widely used in building insulation, medical facilities, transportation, aerospace, and home appliances.

[0003] Vacuum insulation panels are mainly composed of a core material, a barrier membrane, and a getter. The core material and getter are placed in a membrane bag, and then vacuum-sealed and folded. With the development of modern technology, the frequency of use of vacuum insulation panels is increasing, and therefore, the application scenarios are also gradually expanding. To ensure that the insulation panels can be used normally in various scenarios, their functions and structures are constantly changing to better meet the needs of use.

[0004] Existing vacuum insulation panels require pre-determining their size based on the intended use scenario, and then preparing them according to specifications before application. This method makes the application of vacuum insulation panels inflexible. Furthermore, many vacuum insulation panels are not modular and are large in size and weight, making them unsuitable for attaching to the surfaces of appliances and other components. It is also inconvenient for operators to install vacuum insulation panels on the surfaces of appliances and other components. Therefore, a modular vacuum insulation panel structure is needed to solve these practical application problems. Utility Model Content

[0006] This application provides a modular vacuum insulation panel, comprising: a core material, a barrier membrane, a getter, and a membrane bag;

[0007] The barrier membrane is disposed between the core material and the getter, and the core material, barrier membrane and getter are packaged in the membrane bag and vacuum-sealed with the membrane bag;

[0027] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations, however, can be implemented in many different forms and should not be construed as limited to the examples set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art. The features, structures, or characteristics described in connection with the examples can be combined in any suitable manner in one or more implementations. In the following description, numerous specific details are provided to give a thorough understanding of the example implementations.

[0028] The vacuum insulation board is mainly composed of a core material, a barrier film and a getter. The core material and the getter are packaged in a film bag, vacuumized and sealed to form the vacuum insulation board. In the prior art, the size of the vacuum insulation board is determined according to the use scene, and the vacuum insulation board is prepared in advance according to the size specification for application. This way is not flexible for the application of the vacuum insulation board, and many vacuum insulation boards cannot be assembled, and the volume and weight are large, which is not conducive to attaching to the surface of household appliances and other components, and is not convenient for the operator to attach the vacuum insulation board to the surface of the household appliances and other components. Therefore, a combinable and splicable vacuum insulation board structure is needed to solve such practical application problems.

[0029] To solve the above problems, the embodiment of the present application provides a combinable and splicable vacuum insulation board, as shown in Figure 1 The combinable and splicable vacuum insulation board in the embodiment comprises a core material, a barrier film, a getter and a film bag. The barrier film is arranged between the core material and the getter, and the core material, the barrier film and the getter are sleeved in the film bag and are vacuum attached to the film bag.

[0030] Specifically, the core material is the main insulation layer of the vacuum insulation board, and the heat preservation performance of the core material is determined by the material. In the embodiment, the core material is designed to have a specific shape (i.e. a special shape) to adapt to the complex surface of different household appliance components. The barrier film is arranged between the core material and the getter to effectively prevent gas molecules from passing through and maintain the stability of the vacuum environment. The getter is used to absorb the residual gas molecules during the packaging process and the gas that may penetrate during use, ensuring the long-term and efficient insulation of the vacuum insulation board. The film bag is used to package the core material, the barrier film and the getter together, and a tight vacuum attachment structure is formed through vacuumizing treatment.

[0031] The core material is provided with a clamping portion 10, the clamping portion 10 is provided with a groove 11 and / or a protrusion 12, the barrier film and the film bag are attached to the outer contour of the core material, and the vacuum insulation board is consistent with the shape of the core material; two adjacent vacuum insulation boards are clamped through the groove 11 and the protrusion 12 corresponding to the groove 11.

[0032] The clamping portion 10 is designed on the edge or a specific position of the core material, and the clamping portion 10 comprises a groove 11 and / or a protrusion 12. The clamping portion not only enhances the structural strength of the vacuum insulation board, but more importantly, provides a splicing structure between adjacent vacuum insulation boards. The groove 11 and the protrusion 12 are matched in shape to receive and fix the protruding part of the adjacent vacuum insulation board. The protrusion 12 corresponds to the groove 11, and the tight connection between the vacuum insulation boards is achieved by inserting into the groove.

[0033] Two adjacent vacuum insulation panels are spliced by the snap connection of the groove 11 and the protrusion 12. This design not only simplifies the installation process, but also allows users to freely combine vacuum insulation panels of different shapes and sizes according to actual needs, greatly improving the flexibility and applicability of vacuum insulation panels.

[0034] Further, the barrier film is attached to the film bag, and the barrier film and the film bag are tightly attached to the outer contour of the core material, ensuring the integrity and sealing of the entire structure. At the same time, this attachment method makes the shape of the vacuum insulation panel consistent with the core material, facilitating customization of shapes according to actual needs.

[0035] The application embodiment provides a kind of vacuum insulation panel that can be combined and spliced, specifically for large-volume refrigerator cabinet and other household appliances that require large-area VIP plate, such as deep-freeze refrigerator, transport insulation box, etc. For example, a refrigerator, its side and top need to be attached with vacuum insulation panels to improve the insulation effect. The traditional method may need to customize a whole vacuum insulation panel that completely fits the side and top of the refrigerator, which not only has high cost, but also is difficult to install.

[0036] Using the vacuum insulation panel that can be combined and spliced in this embodiment, multiple small vacuum insulation panels can be customized first according to the shape of the side and top of the refrigerator. The edges of each vacuum insulation panel are designed with grooves and protrusions. During installation, only the protrusions of adjacent vacuum insulation panels need to be inserted into the corresponding grooves, and quick and stable splicing can be achieved.

[0037] In this way, not only the manufacturing cost is reduced, but also the installation efficiency is greatly improved. At the same time, since the vacuum insulation panels can be flexibly combined, they can well adapt to the complex shape of the side and top of the refrigerator, ensuring the best insulation effect.

[0038] In summary, the structure of the vacuum insulation panel that can be combined and spliced in this embodiment successfully solves the problems of insufficient flexibility, non-splicing, and large volume and weight of existing vacuum insulation panels in application through innovative design of the snap connection part, providing an efficient and convenient solution for the insulation of household appliances and other components.

[0039] In some embodiments of the present application, the shape of the groove 11 and / or the protrusion 12 is any one of a triangle, a square, and a trapezoid.

[0040] Specifically, the triangular design is known for its stable geometric structure, which can provide good structural support and stability. During splicing, the triangular groove and protrusion can form a tight and firm snap connection, effectively preventing relative movement or misalignment between vacuum insulation panels. It is suitable for scenarios that require high structural strength and stability, such as the edges or corner parts of household appliances. The triangular shape can also disperse stress to some extent, reducing the risk of damage to the vacuum insulation panel caused by external forces.

[0041] The square design is simple and easy to process and manufacture. The matching of square grooves and protrusions can provide uniform contact area, ensuring the flatness and sealing of the splicing between vacuum insulation panels. It is suitable for scenes with high requirements for splicing accuracy and flatness, such as flat parts of household appliances. The square shape makes the splicing process more intuitive and easy to operate, improving installation efficiency.

[0042] The trapezoidal design has a guiding effect, facilitating the rapid alignment and splicing between vacuum insulation panels. The trapezoidal groove can gradually guide the protruding part to enter until it reaches the fully connected state. It is suitable for scenes that require rapid splicing and disassembly, such as household appliance components that need to be frequently replaced or maintained. The trapezoidal shape reduces friction and resistance during splicing, making the operation smoother and labor-saving.

[0043] From the above, it can be seen that the shape of the groove 11 and / or protrusion 12 of the vacuum insulation panel provided by the present application can be selected according to the actual use scene, not only meeting the needs of different application scenes, but also improving the flexibility and applicability of the vacuum insulation panel. In actual application, according to the shape, size and functional requirements of household appliances, appropriate groove and protrusion shapes can be selected for customization and splicing.

[0044] In some embodiments of the present application, the groove 11 includes a single-sided groove and a double-sided groove, and the protrusion 12 includes a single-sided protrusion and a double-sided protrusion.

[0045] One side of the vacuum insulation panel with a single-sided protrusion is inserted into the groove 11 of the vacuum insulation panel with a single-sided groove or a double-sided groove through the protrusion 12, to perform single-sided splicing.

[0046] Both sides of the vacuum insulation panel with double-sided protrusions are inserted into the grooves 11 of two vacuum insulation panels with single-sided grooves or double-sided grooves through the protrusions 12, to perform double-sided splicing.

[0047] Specifically, referring to Figure 2 The single-sided protrusion is used to match with the single-sided groove to realize single-sided splicing between vacuum insulation panels. This design is suitable for scenes that require splicing in a single direction, such as straight edges or single-sided curved parts of household appliances. Since only single-sided splicing needs to be considered, the installation process is simpler and faster, reducing operational complexity and time cost. The design of single-sided protrusion and groove allows the vacuum insulation panel to adjust the angle and position flexibly during splicing, adapting to different shape and size requirements.

[0048] For example, when a vacuum insulation panel needs to be attached to the side of a refrigerator. Since the side of the refrigerator usually has straight edges and a certain degree of curvature, a vacuum insulation panel with a single-sided protrusion and groove can be chosen for splicing. First, customize the vacuum insulation panel according to the shape and size of the refrigerator side, ensuring that the position of the protrusion and groove matches the contour of the refrigerator. Then, start splicing along the straight edge of the refrigerator side, insert the single-sided protrusion into the corresponding single-sided groove, and complete the attachment of the entire side in sequence. This splicing method is not only efficient, but also ensures the close fit and good thermal insulation effect between the vacuum insulation panels.

[0049] Further, the double-sided protrusion design is used to match the double-sided groove to achieve double-sided splicing between vacuum insulation panels. This design is suitable for scenarios that require splicing in two directions simultaneously, such as the corner parts of household appliances or complex-shaped surfaces. The splicing method of double-sided protrusion and groove provides stronger structural support and stability, ensuring that the vacuum insulation panels are not easily loose or deformed after splicing. Double-sided splicing can form a more tightly contacted surface, reducing gas permeation and heat loss, and improving the thermal insulation performance of the vacuum insulation panel.

[0050] Continuing with a specific implementation example, when a vacuum insulation panel needs to be attached to the top of a refrigerator, its shape is usually a rectangular plane, but corners are formed at the four corners. In order to attach the vacuum insulation panel to improve the thermal insulation effect, we can choose a vacuum insulation panel with double-sided protrusions and grooves for splicing. First, customize the vacuum insulation panel according to the shape and size of the refrigerator top, ensuring that the position of the protrusion and groove matches the contour of the washing machine. Then, start splicing from one corner of the refrigerator top, insert the double-sided protrusions into the corresponding double-sided grooves at the same time, and complete the attachment of the entire top in sequence. At the corner part, the splicing method of double-sided protrusion and groove can ensure the close fit and stability between the vacuum insulation panels, thereby improving the overall thermal insulation effect of the vacuum insulation panel.

[0051] Referring to Figure 3 It can be understood that the vacuum insulation panels can also be spliced with one side as a groove 11 and the other side as a protrusion 12. This splicing can not require the selection of the type of vacuum insulation panel, and is more flexible.

[0052] In some embodiments of the present application, the direction of the groove 11 and / or the protrusion 12 is one or more of the length direction, width direction or height direction of the core material.

[0053] It can be understood that when the protrusions and grooves are arranged along the length direction of the core material, they can effectively enhance the structural stability of the vacuum insulation panel in the longitudinal direction, especially in application scenarios that need to bear larger longitudinal pressure or tension. This design is particularly suitable for the splicing of long strip structures, such as refrigerator side walls, air conditioner pipes, etc., which can ensure that the vacuum insulation panel maintains straightness and flatness after splicing.

[0054] When the protrusions and grooves are arranged along the width direction of the core material, they can significantly enhance the connection strength of the vacuum insulation panel in the transverse direction, especially in application scenarios that need to bear larger transverse load or shear force. This design is suitable for the splicing of wide structures, such as large refrigeration door leaves, air conditioning unit side plates, etc., which can ensure the integrity and sealing of the vacuum insulation panel after splicing.

[0055] When the protrusions and grooves are arranged along the height direction of the core material, they can optimize the splicing effect of the vacuum insulation panel in the vertical direction, especially in application scenarios that need to bear larger vertical pressure or gravity load. This design is suitable for the stacking and splicing of multi-layer structures, such as refrigerator tops, refrigerated truck compartments, etc., which can ensure the close fit and stability between the layers of vacuum insulation panels.

[0056] In this embodiment, taking the refrigerated truck compartment as an example, in order to enhance its thermal insulation performance and carrying capacity, vacuum insulation panels with protrusions and grooves in the height direction can be selected for splicing. First, the vacuum insulation panels are customized according to the size and shape of the compartment, ensuring that the protrusions and grooves are arranged along the height direction of the compartment. Then, the vacuum insulation panels are stacked and spliced in sequence to form a continuous insulation layer. During the splicing process, the close fit of the protrusions and grooves not only improves the insulation effect of the compartment, but also effectively prevents deformation and gaps caused by the weight of goods or vibration during driving.

[0057] In some embodiments of the present application, the number of grooves 11 and / or protrusions 12 is at least two. When the number of protrusions and grooves is at least two, they can achieve the fixation and connection of the vacuum insulation panel at multiple points. Compared with single-point or small-point fixation, this multi-point fixation method can significantly improve the splicing stability and shear resistance of the vacuum insulation panel. The close fit of multiple protrusions and grooves can form a more continuous and uniform sealing line, effectively preventing gas penetration and heat loss.

[0058] Further, the design of multiple protrusions and grooves allows for more flexible and diverse ways of splicing the vacuum insulation panels. For example, by adjusting the position, direction, and number of protrusions and grooves, different shapes and sizes can be accommodated, achieving more precise splicing results. For household appliances or building structures with complex shapes or irregular contours, the design of multiple protrusions and grooves can provide more flexible and precise splicing solutions, ensuring close fitting and overall aesthetics between the vacuum insulation panels.

[0059] At the same time, the distribution of multiple protrusions and grooves allows the vacuum insulation panels to disperse stress more evenly when under stress, reducing the risk of deformation or damage due to excessive stress at a single point. The design of multiple protrusions and grooves allows the vacuum insulation panels to be positioned and aligned more quickly when splicing, thereby simplifying the installation process and improving work efficiency. When the vacuum insulation panels need to be disassembled or replaced, the close fit of multiple protrusions and grooves ensures firm connection between the vacuum insulation panels, while also facilitating disassembly and replacement operations through appropriate tools or methods.

[0060] In some embodiments of the present application, the size of the single-sided groove and the single-sided protrusion, as well as the size of the double-sided groove and the double-sided protrusion, are interchangeable, and the groove 11 and the protrusion 12 are in interference fit.

[0061] The interchangeable design of the size of the single-sided groove and the single-sided protrusion, as well as the size of the double-sided groove and the double-sided protrusion, means that these structures have a unified size standard and tolerance range during the manufacturing process. This allows the vacuum insulation panels to be more accurately matched and docked when splicing, avoiding splicing errors and loose problems caused by inconsistent sizes.

[0062] Interference fit refers to the gap between the groove and the protrusion being less than zero, i.e. the protrusion part needs to be slightly "pressed" into the groove part to form a tight connection. This fitting method can ensure close fitting and firm connection between the vacuum insulation panels, effectively preventing gaps and air leakage caused by external forces or temperature changes.

[0063] In this embodiment, under the joint action of interference fit and interchangeability, the connection between the vacuum insulation panels is more secure, reducing the pathways for gas permeation and heat loss. This helps to improve the energy efficiency and energy saving effect of household appliances or building structures. By ensuring that each vacuum insulation panel is accurately and securely spliced together, the quality and uniformity of the entire insulation layer are significantly improved. This helps to reduce the decline in insulation performance and energy loss caused by improper splicing.

[0064] In some embodiments of the present application, the edges and corner positions of the groove 11 and the protrusion 12 are provided with chamfers or fillets.

[0065] The chamfered or rounded design can significantly reduce stress concentration at the groove and protruding edge and corner positions. During the splicing process of the vacuum insulation panel, these positions are often the most concentrated areas of stress, prone to deformation or damage. By chamfering or rounding, stress can be effectively dispersed, improving the deformation resistance and durability of the vacuum insulation panel.

[0066] Chamfering or rounding allows the groove and protrusion to be more smoothly docked during splicing, reducing the difficulty and error caused by shape mismatch. This helps to improve splicing efficiency and quality, ensuring tight fitting and firm connection between vacuum insulation panels. At the same time, it can also improve the aesthetics of the vacuum insulation panel. By optimizing the shape of the edge and corner, the entire vacuum insulation panel looks more rounded and smooth, meeting modern aesthetic requirements.

[0067] In some embodiments of the present application, an edge sealing strip is also included, which is arranged at the gap after the butt joint of the two adjacent vacuum insulation panels.

[0068] By setting the edge sealing strip, the sealing performance of the vacuum insulation panel after splicing can be further improved. Even if there is a small gap between the vacuum insulation panels, the edge sealing strip can effectively fill these gaps and prevent gas penetration and heat loss. This is crucial for maintaining the thermal insulation performance of the vacuum insulation panel.

[0069] Further, the edge sealing strip usually has good waterproof and moisture-proof performance, which can prevent moisture and humidity from entering the interior of the vacuum insulation panel, thereby prolonging the service life of the vacuum insulation panel. The edge sealing strip can also enhance the connection strength between the vacuum insulation panels, making the entire insulation layer more stable and reliable. When subjected to external forces, the edge sealing strip can absorb and disperse part of the stress, protecting the vacuum insulation panel from damage.

[0070] In some embodiments of the present application, a positioning mark is also included, which is arranged on the surface or edge of the vacuum insulation panel. The positioning mark is a color mark or a digital code.

[0071] The positioning mark can greatly simplify the installation process of the vacuum insulation panel. Through color marking or digital coding, the correct position and splicing order of the vacuum insulation panel can be clearly indicated, avoiding the cost of rework and repair due to installation errors. The positioning mark can also improve the splicing accuracy between the vacuum insulation panels. During the splicing process, accurate alignment and positioning can be performed according to the positioning mark, ensuring tight fitting and firm connection between the vacuum insulation panels. This helps to improve the uniformity and thermal insulation performance of the entire insulation layer.

[0072] Through the positioning marks, the positions and numbers of each vacuum insulation plate can be easily identified, which is convenient for subsequent maintenance and management. When the vacuum insulation plate needs to be replaced or repaired, the corresponding position can be quickly located, thereby improving work efficiency and accuracy.

[0073] From the above, it can be seen that the application provides a vacuum insulation plate that can be combined and spliced, which comprises a core material, a barrier film, a getter and a film material bag; the core material is provided with a clamping part, the clamping part is provided with a groove and / or a protrusion, the barrier film and the film material bag are attached to the outer contour of the core material, and the vacuum insulation plate is consistent with the shape of the core material. Two adjacent vacuum insulation plates are clamped through the groove and the protrusion corresponding to the groove. The application directly sets the groove and the protrusion on the vacuum insulation plate, directly splices and installs, clamps the protrusion on one side of the vacuum insulation plate into the groove on the other side of the vacuum insulation plate to position it, so as to prevent deviation. The vacuum insulation plate with this butt joint structure does not need to increase other components, and is modified on the vacuum insulation plate itself, which can well solve the problem that the traditional vacuum insulation plate is not flexible enough in application, and effectively reduces the inconvenience caused by the problem of too large and too heavy vacuum insulation plates in actual use, which is of great convenience to actual operators and actual application scenarios, thereby improving the installation efficiency and increasing the scene application rate.

It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the disclosure being indicated by the following claims.
