Description

Technical Field

[0001] This application relates to the field of insulated refrigerator technology, and more particularly to an insulated refrigerator comprising a glass fiber foam layer. Background Technology

[0002] A thermal refrigerator is a refrigeration device designed to maintain a stable internal temperature. It not only possesses the basic functions of a regular refrigerator, such as refrigeration and preservation, but also emphasizes insulation performance, meaning it can maintain a stable internal temperature for extended periods even during power outages or when there are significant fluctuations in external temperature. This characteristic makes thermal refrigerators widely applicable in various special situations. For example, in areas with frequent power outages or unstable power supply, thermal refrigerators can serve as backup refrigeration equipment in homes, ensuring the freshness and safety of food. In the catering and supermarket industries, thermal refrigerators can be used to store perishable foods such as meat, seafood, and vegetables to maintain their freshness and taste. In the fields of medicine and biotechnology, thermal refrigerators can be used to store vaccines, biological reagents, and other items requiring specific temperature preservation. In scientific research experiments, thermal refrigerators can be used to store experimental samples and reagents to ensure the accuracy and reliability of experimental results. Thermal refrigerators also have wide applications in other industries.

[0003] Insulated refrigerators are typically made of high-efficiency insulation materials, such as fiberglass foam layers and polyurethane foam layers. These materials have excellent thermal insulation properties, effectively reducing heat exchange between the inside and outside of the refrigerator. Simultaneously, insulated refrigerators are equipped with advanced refrigeration and temperature control systems to ensure that the internal temperature remains within a set range. The long-lasting insulation performance of insulated refrigerators is achieved by filling the refrigerator walls with foam layers, such as... Figure 2 The structure shown allows for the filling and sealing of a foamed layer into the refrigerator wall during manufacturing, thus achieving long-lasting heat preservation.

[0004] like Figure 4 As shown, currently, when filling the filling cavity of the box wall with the cut foam layer, one end of the foam layer is appropriately compressed and inserted into the opening of the filling cavity, and then the foam layer is pushed to fill the entire filling cavity. Finally, the opening is sealed with a sealing plate and rivets. However, during the current process of compressing and inserting the side end of the foam layer into the filling cavity and pushing it in, because the two sides of the foam layer are usually provided with protective surface layers, the self-expansion of the foam layer during the filling process will press the protective surface layers against the inner wall of the filling cavity. During the long-distance pushing filling process, the continuous friction between the insulation surface layer and the inner wall surface will cause the insulation surface layer to curl backward (e.g., Figure 5As shown in the figure, the foam layer is squeezed. After the filling is completed, the curled part of the protective surface layer cannot unfold on its own, and the inside of the filling cavity cannot be directly observed. Therefore, the curled part cannot be completely filled in the filling cavity, which affects the heat preservation effect of the refrigerator and increases energy consumption. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide an insulated refrigerator containing a glass fiber foam layer, in which the protective surface of the foam layer is isolated from the inner wall of the filling cavity during the foam layer filling process, solving the problem of the protective surface layer curling due to contact friction, thereby achieving full filling of the filling cavity, improving the insulation effect and reducing energy consumption.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a refrigerator with a glass fiber foam layer, wherein each refrigerator wall has a filling cavity filled with the glass fiber foam layer, one side of the filling cavity has an opening, an isolation device is provided between the end of the glass fiber foam layer that penetrates into the filling cavity and the inner wall of the filling cavity, and a removable sealing plate is provided at the opening.

[0007] Preferably, the insulating device is a U-shaped heat insulation plate that circumferentially covers the glass fiber foam layer and extends into the filling cavity on one end face and on both side walls of a certain width.

[0008] Preferably, the sealing plate can be embedded into the opening, and an insert is provided on both end faces of the sealing plate, and an embedding cavity is formed on the inner side wall of the filling cavity to cooperate with the insert.

[0009] Preferably, a drive plate flush with the opening is provided on the outer side of the sealing plate, and the upper and lower surfaces of the drive plate extend to the outer side of the sealing plate.

[0010] The beneficial effects of this application are: by using an isolation device to isolate the side end face of the glass fiber foam layer embedded in the filling cavity from the inner wall surface of the filling cavity, the protective surface layer of the foam layer will not curl due to contact friction between the protective surface layer of the foam layer and the inner wall surface of the filling cavity during the continuous pushing of the foam layer filling process, thereby achieving full filling of the filling cavity, improving the heat preservation effect and reducing energy consumption.

[0011] The removable sealing plate allows the opening of the filling cavity to be opened smoothly, thus enabling the replacement of the foam layer after long-term use and reducing the refrigerator's energy consumption. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] See attached document Figures 1-11The refrigerator shown contains a glass fiber foam layer, and each wall of the refrigerator has a filling cavity 1 filled with the glass fiber foam layer. One side of each filling cavity 1 has an opening 1a. The cut glass fiber foam layer is inserted into the filling cavity 1 through the opening and pushed until it completely fills the cavity 1. To address the problem that the filling state within the cavity is currently unobservable, causing the insulation layer to curl due to continuous contact friction between the protective surface layer and the inner wall of the filling cavity 1 during filling, resulting in incomplete filling and reduced insulation performance and increased energy consumption, this application provides an isolation device between the end of the glass fiber foam layer that penetrates into the filling cavity 1 and the inner wall of the filling cavity 1. This isolation device isolates the side end of the glass fiber foam layer embedded in the filling cavity 1 from the inner wall of the filling cavity 1. Therefore, during the continuous pushing process of filling the foam layer, the problem of the protective surface layer curling due to contact friction between the foam layer and the inner wall of the filling cavity 1 is prevented, thus achieving full filling of the cavity, improving insulation performance, and reducing energy consumption.

[0027] Currently, after the foam layer is filled into the filling cavity, the sealing plate is fixed to the opening with rivets. However, in the long-term use environment of the refrigerator, it is inevitable to be exposed to a humid and hot environment, which causes the insulation performance of the foam layer to decline, thereby continuously increasing the energy consumption of the refrigerator. The fixed sealing plate is easy to damage the filling cavity when disassembled, so it is usually difficult to replace the foam layer. Therefore, in order to solve this problem, this application provides a detachable sealing plate 2 at the opening 1a. The opening 1a of the filling cavity 1 can be opened smoothly through the detachable sealing plate 2, thereby realizing the replacement of the foam layer and reducing the energy consumption of the refrigerator.

[0028] Specifically, such as Figure 6-7 As shown, the isolation device is a U-shaped heat insulation plate 3 (preferably a rubber or wood board with a lower thermal conductivity than metal) that circumferentially covers the glass fiber foam layer and extends into one end face and two side walls of the filling cavity 1. This U-shaped heat insulation plate 3 achieves isolation between the foam layer and the inner side wall of the filling cavity 1 through continuous frictional contact, thereby solving the problem of the protective surface layer curling and affecting the integrity of the filling due to continuous contact, improving the insulation effect of the refrigerator after filling, and reducing energy consumption.

[0029] Specifically, such as Figure 9-10As shown, the sealing plate 2 can be embedded into the opening 1a. Embedded bodies 21 are provided on both end faces of the sealing plate 2, and an embedding cavity 1b is formed on the inner wall of the filling cavity 1 to accommodate the embedded bodies 21. After the foam layer is filled, the sealing plate 2 is pressed into the filling cavity 1, so that the embedded bodies 21 at both ends can be embedded into the embedding cavity 1b after bending. After the sealing plate 2 recovers its deformation, it presses the embedded bodies 21 on both sides into the embedding cavity 1b to achieve sealing. However, after prolonged use, as energy consumption increases and the insulation effect of the foam layer decreases, the sealing plate 2 is driven outwards, causing it to bend outwards, allowing the embedded bodies 21 at both ends to detach from the embedding cavity 1b, enabling quick disassembly of the sealing plate 2. The foam layer can then be removed and replaced.

[0030] For example, if the sealing plate 2 extends beyond the side of the refrigerator door, it may cause a problem where a side-by-side refrigerator cannot close smoothly. Figure 9-10 As shown, a drive plate 22, flush with the opening 1a, is provided on the outer surface of the sealing plate 2. The upper and lower surfaces of the drive plate 22 extend to the outer side of the sealing plate 2. A step is formed between the upper and lower surfaces of the drive plate 22 and the outer side of the sealing plate 2, making the drive plate 22 easy to grip and serving as a handle, so that the sealing plate 2 can be easily driven outward and disassembled during replacement. At the same time, the fact that the drive plate 22 is flush with the opening 1a facilitates the smooth closing of items such as side-by-side refrigerators.

[0031] The principle of this application is as follows: During the refrigerator manufacturing process, a U-shaped heat insulation plate 3 is wrapped around the side end of the cut foam layer, and then the whole is embedded into the filling cavity 1. The U-shaped heat insulation plate 3 is used to isolate the foam layer from the inner wall of the filling cavity 1, which solves the problem of the surface curling of the foam layer caused by direct contact. After filling is completed, the sealing plate 2 is removable by embedding the insert at the side end of the sealing plate 2 into the embedding groove. This facilitates the solution of the problem of the decreased heat insulation performance of the foam layer and the increase in energy consumption after long-term use of the refrigerator.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
