Description

Technical Field

[0001] This utility model relates to the field of freezer technology, and in particular to a freezer with a convenient inner liner assembly. Background Technology

[0002] The assembly of the inner liner of a horizontal freezer is a crucial step in the freezer manufacturing process, directly affecting the freezer's insulation performance and lifespan. In existing technologies, the inner liner is typically assembled by first fitting it into the slot on the front frame, and then securing the connection between the inner liner and the front frame with tape. However, because the connection between the front frame and the inner liner has a near 90-degree angle, and the tape needs to be wrapped around this angle, gaps can occur during the foaming process. The tape is not tightly adhered to the front frame and the inner liner, leaving gaps where the foaming liquid cannot fully fill. This can easily lead to delamination at the corner, affecting product quality. Utility Model Content

[0003] In view of this, in order to solve the above-mentioned technical problems, this utility model provides a refrigerator that allows for convenient assembly of the inner liner without the need for fixing with tape.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A refrigerator with a convenient inner liner assembly includes a cabinet body and a door body rotatably connected to the cabinet body. The cabinet body includes an outer box with a top opening and an inner liner, as well as a cabinet frame located on the top of the outer box and the inner liner. The inner liner is located inside the outer box, and there is a foam gap between the outer side wall of the inner liner and the inner side wall of the outer box. The tops of the outer box and the inner liner are both snapped onto the cabinet frame. The top of the inner liner is provided with flanges perpendicular to the side walls of the inner liner. The cabinet frame is provided with four locking strips with slots, and adjacent locking strips are perpendicular to each other. The flanges can be snapped into the slots corresponding to the locking strips.

[0006] The aforementioned technical solution greatly simplifies the assembly process between the inner liner and the outer box by designing a snap-fit ​​connection method where the flanges around the top of the inner liner mate with the slots on the outer frame's retaining strips. This snap-fit ​​structure eliminates the need for complex fasteners, such as tape wrapping or additional installation steps; assembly is simply completed by aligning the flanges with the slots and snapping them in, significantly improving production efficiency. Furthermore, since no tape is needed, there are no gaps between the retaining strips and the tape at the corners connecting the outer frame and the inner liner, allowing the foaming liquid to completely fill and support the inner liner, thus eliminating delamination and improving product quality. In addition, the precise fit between the retaining strips and slots ensures the accurate positioning of the inner liner within the box, preventing misalignment or tilting caused by manual installation errors. This not only enhances the overall aesthetics of the freezer but also guarantees the uniformity and insulation performance of subsequent foaming processes.

[0007] Furthermore, the length of the flange is less than the width of the inner liner, and a first clearance notch is provided between two adjacent flanges.

[0008] In the above technical solution, the design of the flange and the first clearance notch can reduce the space occupied by the top edge of the inner liner, and at the same time make the assembly of the inner liner more convenient. Since the flange needs to be inserted into the slot by means of compression, the independent design of each flange allows it to be assembled with the corresponding slot strip individually, thereby improving the fault tolerance rate of the inner liner assembly.

[0009] Furthermore, the box frame is provided with at least one limiting rib, which is located at the first clearance notch and matches the edge of the inner liner.

[0010] In the aforementioned technical solution, the design of the limiting ribs significantly enhances the stability of the freezer structure. As additional support points, the limiting ribs effectively prevent displacement or deformation of the inner liner under external forces, ensuring the freezer's stability and reliability during long-term use. Furthermore, the presence of the limiting ribs provides a clear positioning reference for the inner liner installation. During assembly, operators can more easily align the edges of the inner liner with the limiting ribs, ensuring a precise fit between the inner liner and the cabinet frame.

[0011] Furthermore, the card strip has an "L" shaped cross-section, and the card strip and the bottom of the box frame together form the card groove, with a second clearance notch between two adjacent card strips.

[0012] In the above technical solution, the L-shaped retaining strip provides additional support and rigidity, enabling the retaining groove to maintain a stable shape and position when subjected to the weight or external forces of the inner liner or other components, preventing deformation or damage. Simultaneously, the L-shaped retaining strip also makes the opening of the retaining groove wider, facilitating easy sliding of the inner liner or other components to be installed. The second clearance notch between adjacent retaining strips provides a certain amount of redundant space for the assembly of the inner liner's flange, thus further facilitating the assembly of the inner liner.

[0013] Furthermore, the inner liner includes an integrally bent first plate and a second plate, which are joined together to form a box-shaped structure with an open top.

[0014] In the above technical solution, assembling the inner liner into two parts can effectively reduce the deformation of the inner liner during assembly. The integrally bent first and second plates can reduce the number of seams between the plates, thereby reducing structural weaknesses caused by improper seam treatment, ensuring that the inner liner has a certain strength, enabling the inner liner to withstand greater pressure and impact, and extending the service life of the freezer.

[0015] Furthermore, the connecting ends of the first plate and the second plate are respectively provided with a first bend and a second bend in opposite directions, and the first bend and the second bend can be interlocked with each other.

[0016] In the above technical solution, the design of the first bend and the second bend allows them to interlock when connected, forming a mechanical locking effect. This not only enhances the stability of the connection but also reduces the risk of loosening or falling off due to long-term use or external force, thereby ensuring the stability and durability of the inner liner structure. At the same time, it simplifies the assembly of the inner liner; simply align the two parts and press gently to achieve a quick and stable connection.

[0017] Furthermore, the side of the box frame located in the foaming gap is provided with a plurality of first buckles, and the plurality of first buckles are spaced apart.

[0018] In the above technical solution, the design of the first buckle can better fix the foam material. After the foam material is cured, it can stably hook the cured foam material. It can not only serve as a fixing device during the foaming process to prevent the inner liner from moving and deforming, but also play a role in enhancing the structural strength after the foaming is completed.

[0019] Furthermore, the outer casing frame is provided with a plurality of second buckles on one side located in the foaming gap, and the plurality of second buckles are all close to the edge of the outer casing frame. The inner side of the outer casing is provided with a plurality of grooves that cooperate with the plurality of second buckles.

[0020] In the above technical solution, the design of the second buckle and groove simplifies the assembly process of the freezer. During assembly, the operator only needs to align the second buckle on the front frame with the groove on the inside of the outer box and then press gently to achieve a quick connection. This assembly method, which requires no additional fasteners or complex tools, not only improves assembly efficiency but also reduces assembly costs.

[0021] Furthermore, the side of the box frame located in the foaming gap is provided with multiple ribs, which are distributed in a ring and close to the inner periphery of the box frame.

[0022] In the above technical solution, the ribs can effectively prevent the foaming liquid from leaking out during the curing process of the foamed material. At the same time, they can significantly enhance the structural strength of the box frame, making it more stable and less prone to deformation when facing external pressure or impact.

[0023] Furthermore, a door seal is provided on the side of the door body near the box body, and the door seal is arranged in a ring shape and close to the edge of the door body.

[0024] In the above technical solution, the door seal design effectively improves the sealing performance between the door and the cabinet. When the door is closed, the door seal can be tightly compressed between the door frame and the door, forming an effective sealing barrier to prevent cold air leakage and outside air intrusion, thereby maintaining the stability of the internal temperature and energy efficiency of the freezer.

Detailed Implementation

[0033] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0034] A preferred embodiment of this utility model is as follows.

[0035] Please refer to Figures 1-4 A refrigerator with a convenient inner liner 12 assembly includes a cabinet body 1 and a door 2 rotatably connected to the cabinet body 1. The cabinet body 1 includes an outer box 11 with a top opening and an inner liner 12, and a cabinet frame 13 located on the top of the outer box 11 and the inner liner 12. The inner liner 12 is located inside the outer box 11, and there is a foam gap 14 between the outer side wall of the inner liner 12 and the inner side wall of the outer box 11. The tops of the outer box 11 and the inner liner 12 are both snapped onto the cabinet frame 13. The top of the inner liner 12 is provided with flanges 15 perpendicular to the side walls of the inner liner 12. The cabinet frame 13 is provided with four locking strips 131 with slots. The two adjacent locking strips 131 are perpendicular to each other, and the flanges 15 can be snapped into the slots of the corresponding locking strips 131.

[0036] This embodiment simplifies the assembly process between the inner liner 12 and the outer casing 11 by designing a snap-fit ​​connection method where the flanges 15 around the top of the inner liner 12 engage with the slots of the retaining strips 131 on the outer frame 13. This snap-fit ​​structure eliminates the need for complex fasteners, such as tape wrapping or additional installation steps; assembly is completed simply by aligning the flanges 15 with the slots and snapping them in, significantly improving production efficiency. Furthermore, since no tape is needed, there are no gaps between the retaining strips and the tape at the corners connecting the outer frame 13 and the inner liner 12, allowing the foaming liquid to completely fill and support the inner liner 12, thus eliminating delamination and improving product quality. In addition, the precise fit between the retaining strips 131 and the slots ensures the accurate position of the inner liner 12 within the casing 1, preventing misalignment or tilting caused by manual installation errors. This not only enhances the overall aesthetics of the freezer but also ensures the uniformity and insulation performance of subsequent foaming processes.

[0037] It should be noted that the inner liner 12 has a flexible structure. When engaging the flange 15 with the slot, the flange 15 can be bent and squeezed to ensure it is fully engaged in the slot. Alternatively, after assembling the inner liner 12, tape can be used to further secure the connection between the flange 15 and the slot. In this case, the angle between the clip 131 and the flange 15 has a negligible impact and will not create large gaps that would affect the filling of the foam material.

[0038] In this embodiment, the length of the flange 15 is less than the width of the inner liner 12, and a first clearance notch 151 is provided between two adjacent flanges 15. The inner liner 12 has four edges on its sides, that is, the inner liner 12 has four sides, and correspondingly has four flanges 15, each flange 15 being independent and not interfering with each other.

[0039] The design of the flange 15 and the first clearance notch 151 in this embodiment can reduce the space occupied by the top edge of the inner liner 12, and also make the assembly of the inner liner 12 more convenient. Since the flange 15 needs to be inserted into the slot by means of compression, the independent design of each flange 15 allows it to be assembled with the corresponding card strip 131 individually, thereby improving the fault tolerance rate of the inner liner 12 assembly.

[0040] Please refer to Figure 3 In this embodiment, the box frame 13 is provided with at least one limiting rib 132, which is located at the first clearance notch 151 and matches the edge of the inner liner 12. Specifically, this embodiment provides four limiting ribs 132, which correspond to the four edges respectively.

[0041] The design of the limiting rib 132 significantly enhances the stability of the freezer structure. As an additional support point, the limiting rib 132 effectively prevents the inner liner 12 from shifting or deforming under external forces, ensuring the stability and reliability of the freezer during long-term use. Furthermore, the presence of the limiting rib 132 provides a clear positioning reference for the installation of the inner liner 12. During assembly, operators can more easily align the edges of the inner liner 12 with the limiting rib 132, ensuring a precise fit between the inner liner 12 and the cabinet frame 13.

[0042] In this embodiment, the card strip 131 has an "L" shaped cross-section. The card strip 131 and the bottom of the box frame 13 together form a card groove. A second clearance notch 133 is provided between two adjacent card strips 131. There are four card strips 131, which correspond to four flanges 15 respectively, and the four card strips 131 are arranged in a square structure.

[0043] The L-shaped retaining strip 131 provides additional support and rigidity, enabling the retaining groove to maintain a stable shape and position when subjected to the weight or external force of the inner liner 12 or other components, preventing deformation or damage. Simultaneously, the L-shaped retaining strip 131 also makes the opening of the retaining groove wider, facilitating easy sliding of the inner liner 12 or other components to be installed. The second clearance notch 133 provided between two adjacent retaining strips 131 provides a certain amount of redundant space for the assembly of the inner liner 12's flange 15, thus further facilitating the assembly of the inner liner 12.

[0044] Please refer to Figure 5 In this embodiment, the inner liner 12 includes an integrally bent first plate 121 and a second plate 122, which are spliced ​​together to form a box-shaped structure with an open top.

[0045] In this embodiment, assembling the inner liner 12 into two parts can effectively reduce the deformation of the inner liner 12 during assembly. The integrally bent first plate 121 and second plate 122 can reduce the number of seams between the plates, thereby reducing structural weaknesses caused by improper seam treatment, ensuring that the structure of the inner liner 12 has a certain strength, enabling the inner liner 12 to withstand greater pressure and impact, and extending the service life of the freezer.

[0046] Please refer to Figure 6 It should be noted that the connecting ends of the first plate 121 and the second plate 122 are respectively provided with a first bending part 1211 and a second bending part 1221 with opposite directions, and the first bending part 1211 and the second bending part 1221 can be interlocked with each other.

[0047] The design of the first bend 1211 and the second bend 1221 allows them to interlock when connected, forming a mechanical locking effect. This not only enhances the stability of the connection but also reduces the risk of loosening or falling off due to long-term use or external force, thus ensuring the stability and durability of the inner liner 12 structure. At the same time, it simplifies the assembly of the inner liner 12; simply align the two parts and press gently to achieve a quick and stable connection.

[0048] Please refer to Figure 7 In this embodiment, the side of the box frame 13 located at the foaming gap 14 is provided with a plurality of first buckles 134, which are spaced apart. The design of the first buckles 134 can better fix the foaming material. After the foaming material is cured, they can stably hook the cured foaming material. They can not only serve as a fixing device during the foaming process to prevent the inner liner 12 from moving and deforming, but also enhance the structural strength after the foaming is completed.

[0049] In this embodiment, the box frame 13 is provided with a plurality of second buckles 135 on one side of the foam gap 14. The plurality of second buckles 135 are close to the edge of the box frame 13, and the inner side of the outer box 11 is provided with a plurality of grooves that cooperate with the plurality of second buckles 135.

[0050] The design of the second buckle 135 and the groove simplifies the assembly process of the freezer. During assembly, the operator only needs to align the second buckle 135 on the front frame 13 with the groove on the inside of the outer box 11, and then press gently to achieve a quick connection. This assembly method, which requires no additional fasteners or complicated tools, not only improves assembly efficiency but also reduces assembly costs.

[0051] In addition, multiple ribs 136 are provided on one side of the box frame 13 located in the foaming gap 14. The multiple ribs 136 are distributed in a ring and close to the inner perimeter of the box frame 13. The ribs 136 can effectively prevent the foaming liquid from leaking out during the curing process of the foam material, and at the same time, they can significantly enhance the structural strength of the box frame 13, making it more stable and less prone to deformation when facing external pressure or impact.

[0052] In this embodiment, a door seal is provided on the side of the door 2 near the cabinet 1. The door seal is ring-shaped and close to the edge of the door 2. The design of the door seal effectively improves the sealing performance between the door 2 and the cabinet 1. When the door 2 is closed, the door seal can be tightly compressed between the door frame and the door 2, forming an effective sealing barrier to prevent cold air leakage and outside air intrusion, thereby maintaining the stability of the internal temperature and energy efficiency ratio of the freezer.
