Description

Technical Field

[0001] The utility model relates to the field of refrigerators, in particular to an inner liner structure and a refrigerator. Background Art

[0002] The assembly of the liner of a horizontal freezer is a key step in the freezer manufacturing process, directly affecting the freezer's insulation and service life. The liner is typically assembled with the freezer frame, meaning it's assembled onto the frame. To achieve the freezer's cooling effect, conventional techniques typically incorporate air ducts and air outlets into the liner. Because the liner itself is relatively thin and often flexible, separate openings are required to create these ducts or outlets. A cover is then installed at the opening to create the duct or outlet. This requires a separate mold for the cover, which not only reduces assembly efficiency but also significantly increases the cost of the freezer. Utility Model Content

[0003] In view of this, the present invention provides an inner tank structure and a refrigerator to solve the above technical problems.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A liner structure includes an liner main body with an opening at the top, and a box surface frame arranged on the top of the liner main body, the box surface frame includes an integrally formed frame body and an extension portion, the liner matches the extension portion and is snapped onto the extension portion, the side wall of the extension portion is provided with an air inlet, an air duct cover plate and an air outlet module integrally formed with the extension portion, an air supply channel is formed between the air duct cover plate and the extension portion, the air outlet module connects the air supply channel and the liner, and the air inlet connects the air supply channel.

[0006] In the above technical solution, the frame, extension, and air outlet module in the box face frame are an integrated structure. This design, on the one hand, simplifies the production process and significantly improves the stability and durability of the overall structure. On the other hand, by integrating the air outlet module and the air duct cover with the box face frame, the assembly process of the refrigerator liner is reduced. Only the liner body and the box face frame need to be spliced ​​together, which is simple and efficient. Compared with the traditional structure in which both the air outlet and the air duct are set on the liner body, the utility model does not require the assembly of an additional air outlet cover, which reduces the use of molds and reduces the difficulty of assembly, thereby greatly saving the production cost of the refrigerator and improving the assembly efficiency of the refrigerator.

[0007] Furthermore, there are multiple air outlet modules, and the multiple air outlet modules are spaced apart along the length direction of the side wall of the extension portion.

[0008] In the above technical solution, multiple air outlet modules are spaced apart to form multiple independent air supply points, allowing the cool air to be more evenly distributed throughout the inner tank. This multi-point air supply method effectively avoids the local temperature differences that may be caused by single-point air supply, further improving the air circulation efficiency and temperature uniformity inside the inner tank.

[0009] Furthermore, each of the air outlet modules includes a plurality of air outlet slots, wherein the number of the air outlet slots in each of the air outlet modules increases step by step in a direction away from the air inlet.

[0010] The above technical solution allows the cold air to be more evenly dispersed along the increasing number of outlet slots after entering the air supply duct. The smaller number of outlet slots near the air inlet helps to form the initial cold air flow. As the number of outlet slots increases away from the air inlet, it promotes further dispersion and mixing of the cold air, thus forming a more uniform and stable temperature field inside the liner.

[0011] Furthermore, the progressively increasing number of air outlet slots allows cool air to more effectively reach all areas of the liner during its flow. This is especially true at the far ends or corners of the liner, where the increased number of air outlet slots ensures sufficient cool air supply, improving overall air delivery efficiency and temperature control.

[0012] Furthermore, a plurality of mutually parallel partitions are arranged at intervals on the air duct cover plate, and the plurality of partitions divide the air supply channel into a plurality of sub-channels.

[0013] In the above technical solution, by subdividing the air supply channel into multiple sub-channels, the partition effectively guides the flow direction of the cold air, making the flow of cold air in the air supply channel more orderly and controllable, which helps to reduce turbulence and eddy currents and improve the efficiency and stability of air flow.

[0014] Furthermore, the air outlet slot in each of the air outlet modules corresponds to at least one sub-channel.

[0015] In this technical solution, since each air outlet slot corresponds to at least one sub-channel, the air flow rate of each air outlet slot can be more precisely controlled. By adjusting the size, shape, or number of sub-channels, the air flow rate of each air outlet slot can be finely adjusted, and the air flow rate of each air outlet slot can be ensured to be consistent, thereby meeting the specific temperature requirements of different areas within the liner.

[0016] Furthermore, the inner liner body includes a first enclosure and a second enclosure with flush tops, and a Z-shaped bottom plate, the height of the second enclosure is less than the height of the first enclosure, and the Z-shaped bottom plate is used to close the bottoms of the first enclosure and the second enclosure.

[0017] In the above technical solution, the Z-shaped bottom plate design not only effectively seals the bottoms of the first and second panels, but also, through its unique shape, increases the structural strength of the liner body. The Z-shaped structure provides additional support in both vertical and horizontal directions, making the liner body more stable and able to withstand greater pressure and impact. Furthermore, the structural design of the inner plate body provides ample space for installing equipment such as compressors.

[0018] Furthermore, the bottom edge of the extension portion is provided with a convex edge, which matches the top of the inner liner body, and the convex edge is provided with a slot with an opening facing downward, and the top of the inner liner body can be snapped into the slot.

[0019] In the above technical solution, the snap-fit ​​design between the slot and the top of the liner ensures a tight connection between the extension and the liner body, effectively preventing the infiltration of air or moisture. Furthermore, the slot and snap-fit ​​design make installation of the extension and the liner body simple and quick. No complex fasteners or tools are required; simply align the top of the liner body with the slot and gently push it in to complete the installation.

[0020] Furthermore, the connecting ends of the first enclosure and the second enclosure are respectively provided with a first bending portion and a second bending portion folded in opposite directions, and the first bending portion and the second bending portion can be interlocked.

[0021] In the above technical solution, the design of the first bent portion and the second bent portion enables the two to interlock with each other when connected, forming a mechanical locking effect, which 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 can also simplify the assembly of the inner liner. Just align the two and press lightly to achieve a quick and stable connection.

[0022] Furthermore, an air return port and a drain port are provided at the bottom of the inner tank body.

[0023] In the above technical solution, the design of the return air vent enables effective circulation of air inside the inner tank. The design of the drain port can promptly discharge condensed water formed in the inner tank body to prevent it from accumulating and possibly damaging the contents.

[0024] The utility model also provides a refrigerator, comprising an outer shell, a refrigeration system and a fan, and also comprising the above-mentioned inner liner structure, wherein the inner liner structure is arranged in the outer shell, the air inlet is connected to the fan, and the refrigeration system is connected to the fan.

[0025] In the above technical solution, by integrating the above-mentioned inner liner structure into the refrigerator and closely connecting it with the refrigeration system and fan, the refrigerator's cooling capacity can be significantly improved, and the cold air can be more evenly and efficiently distributed within the inner liner, thereby achieving a fast and stable cooling effect. It can also greatly facilitate the assembly of the refrigerator. The inner liner assembly only requires snapping the inner liner body onto the cabinet frame, which is simple and convenient to operate, effectively improving assembly efficiency and reducing production costs.

DETAILED DESCRIPTION

[0032] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0033] A preferred embodiment of the present utility model is as follows.

[0034] Please refer to Figure 1-Figure 3A liner structure includes an liner main body 1 with an opening at the top, and a box surface frame 2 arranged on the top of the liner main body 1. The box surface frame 2 includes an integrally formed frame body 21 and an extension portion 22. The liner matches the extension portion 22 and is snapped onto the extension portion 22. An air inlet 23, an air duct cover 25, and an air outlet module 24 integrally formed with the extension portion 22 are provided on the side wall of the extension portion 22. An air supply channel is formed between the air duct cover 25 and the extension portion 22. The air outlet module 24 connects the air supply channel and the liner, and the air inlet 23 connects the air supply channel.

[0035] In this embodiment, the frame 21, extension 22, and air outlet module 24 in the box face frame 2 are an integrally molded structure. This design, on the one hand, simplifies the production process and significantly improves the stability and durability of the overall structure. On the other hand, by integrally molding the air outlet module 24 and the air duct cover 25 with the box face frame 2, the assembly process of the refrigerator liner is reduced. Only the liner body 1 and the box face frame 2 need to be spliced ​​together, which is simple and efficient. Compared with the traditional structure in which both the air outlet and the air duct are set on the liner body 1, the present utility model does not require the assembly of an additional air outlet cover, which reduces the use of molds and reduces the difficulty of assembly, thereby greatly saving the production cost of the refrigerator and improving the assembly efficiency of the refrigerator.

[0036] In this embodiment, there are a plurality of air outlet modules 24 , and the plurality of air outlet modules 24 are spaced apart along the length direction of the side wall of the extension portion 22 .

[0037] By setting multiple air outlet modules 24 at intervals, multiple independent air supply points can be formed, so that the cold air can be more evenly distributed in every corner of the inner liner. This multi-point air supply method effectively avoids the local temperature differences that may be caused by single-point air supply, and further improves the air circulation efficiency and temperature uniformity inside the inner liner. In addition, inner liners of different shapes, sizes or layouts may require different air supply strategies. The interval setting of multiple air outlet modules 24 makes it easier for the inner liner structure to adapt to various inner liner designs, and the best air supply effect can be achieved by adjusting the position and number of the air outlet modules 24.

[0038] In this embodiment, each air outlet module 24 includes a plurality of air outlet slots 241 , each air outlet slot 241 having the same size and shape, wherein the number of the air outlet slots 241 in each air outlet module 24 increases step by step in the direction away from the air inlet 23 .

[0039] The above technical solution allows the cold air to be more evenly dispersed along the increasing number of outlet slots 241 after entering the air supply duct. The fewer outlet slots 241 near the air inlet 23 help form the initial cold air flow. As the number of outlet slots 241 increases away from the air inlet 23, it promotes further dispersion and mixing of the cold air, thereby forming a more uniform and stable temperature field inside the liner.

[0040] Furthermore, the progressively increasing number of air outlet slots 241 allows the cool air to more effectively reach all areas of the liner during its flow. This is particularly true at the far ends or corners of the liner, where the increased number of air outlet slots 241 ensures that these areas also receive an adequate supply of cool air, thereby improving overall air supply efficiency and temperature control.

[0041] In this embodiment, a plurality of mutually parallel partitions 251 are provided at intervals on the air duct cover 25, and the plurality of partitions 251 divide the air supply channel into several sub-channels 252. By subdividing the air supply channel into a plurality of sub-channels 252, the partitions 251 effectively guide the flow direction of the cold air, making the flow of the cold air in the air supply channel more orderly and controllable, helping to reduce turbulence and eddy currents, and improving the efficiency and stability of air flow. The design of the plurality of sub-channels 252 enables the cold air to be more evenly distributed in various areas of the inner liner. Each sub-channel 252 undertakes a certain amount of air supply tasks. By rationally designing the position and number of the partitions 251, it can be ensured that the amount of cold air and the wind speed delivered by each sub-channel 252 are basically the same, thereby forming a more uniform temperature field inside the inner liner.

[0042] It should be noted that each air outlet slot 241 in the air outlet module 24 corresponds to at least one sub-channel 252. Since each air outlet slot 241 corresponds to at least one sub-channel 252, the air flow rate of each air outlet slot 241 can be more precisely controlled. By adjusting the size, shape, or number of the sub-channels 252, the air flow rate of each air outlet slot 241 can be finely adjusted, and the air flow rate of each air outlet slot 241 can be ensured to remain consistent, thereby meeting the specific temperature requirements of different areas within the inner tank.

[0043] Please refer to Figure 4-Figure 5 In this embodiment, the inner liner body 1 includes a first enclosure 11 and a second enclosure 12 with flush tops, and a Z-shaped bottom plate 13. The height of the second enclosure 12 is less than that of the first enclosure 11. The Z-shaped bottom plate is used to close the bottoms of the first enclosure 11 and the second enclosure 12.

[0044] The Z-shaped bottom plate 13 not only effectively seals the bottoms of the first and second panels 11, 12, but also, through its unique shape, increases the structural strength of the liner body 1. This Z-shaped structure provides additional support in both vertical and horizontal directions, making the liner body 1 more stable and able to withstand greater pressure and impact. Furthermore, the structural design of the inner panel body provides ample space for installing equipment such as compressors.

[0045] In this embodiment, the bottom edge of the extension portion 22 is provided with a protrusion 27, which matches the top of the inner liner body 1, and the protrusion 27 is provided with a slot with an opening facing downward, and the top of the inner liner body 1 can be snapped into the slot.

[0046] The snap-fit ​​design between the slot and the top of the liner body 1 ensures a tight connection between the extension 22 and the liner body 1, effectively preventing the infiltration of air or moisture. Furthermore, the slot and snap-fit ​​design make installation of the extension 22 and the liner body 1 simple and quick. No complex fasteners or tools are required; simply align the top of the liner body 1 with the slot and gently push it in to complete the installation.

[0047] In this embodiment, the connecting ends of the first enclosure 11 and the second enclosure 12 are respectively provided with a first bending portion 111 and a second bending portion 121 folded in opposite directions, and the first bending portion 111 and the second bending portion 121 can be interlocked.

[0048] The design of the first bend portion 111 and the second bend portion 121 enables the two to interlock when connected, forming a mechanical locking effect, which 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 can also simplify the assembly of the inner liner. Just align the two and press lightly to achieve a quick and stable connection.

[0049] In this embodiment, an air return port 131 and a drain port 132 are provided at the bottom of the inner tank body 1. The design of the air return port 131 enables the air inside the inner tank to form an effective circulation flow. In a refrigerated, frozen or humid environment, condensation water may be generated inside the inner tank. The design of the drain port 132 can discharge this condensation water from the inner tank in a timely manner to prevent it from accumulating and possibly causing damage to the items inside. At the same time, the presence of the drain port 132 also reduces the problem of bacterial growth caused by the accumulation of condensation water, keeping the inside of the inner tank clean and hygienic.

[0050] This embodiment also provides a refrigerator, including a shell, a refrigeration system and a fan, and also includes the above-mentioned inner liner structure, the inner liner structure is arranged in the shell, the air inlet 23 is connected to the fan, and the refrigeration system is connected to the fan.

[0051] By integrating the above-mentioned inner liner structure into the refrigerator and closely connecting it with the refrigeration system and fan, the refrigerator's cooling capacity can be significantly improved, and the cold air can be more evenly and efficiently distributed within the inner liner, thereby achieving a fast and stable cooling effect. It can also greatly facilitate the assembly of the refrigerator. The inner liner assembly only requires snapping the inner liner body 1 onto the cabinet frame 2. This is a simple and convenient operation that can effectively improve assembly efficiency and reduce production costs.
