Description

Technical Field

[0001] The invention relates to the field of refrigerators, and 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 link in the manufacturing process of the freezer, which directly affects the insulation effect and service life of the freezer. The liner usually needs to be matched with the box frame during assembly, that is, the liner is assembled to the box frame. In order to achieve the refrigeration effect of the freezer, in the prior art, structures such as air ducts and air outlets are usually set on the liner. Since the liner itself is relatively thin and mostly a flexible structure, a separate opening is required when setting the air duct or air outlet, and then a cover plate is installed at the opening to form an outlet duct or outlet. This requires a separate mold for the cover plate, which not only has low assembly efficiency, but also greatly increases the cost of the freezer. Summary of the invention

[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 present invention is achieved through the following technical solutions:

[0005] An inner liner structure comprises an inner liner main body with an opening at the top, and a box surface frame arranged on the top of the inner liner main body, the box surface frame comprises an integrally formed frame body and an extension portion, the inner liner matches the extension portion and is snapped onto the extension portion, an air inlet, an air duct cover plate and an air outlet module integrally formed with the extension portion are provided on the side wall of 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 inner 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 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. It is only necessary to splice the liner body with the box face frame, 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 present invention does not need to assemble an additional air outlet cover, 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 a plurality of air outlet modules, and the plurality of air outlet modules are arranged at intervals along the length direction of the side wall of the extension portion.

[0008] In the above technical solution, multiple independent air supply points can be formed by setting multiple air outlet modules at intervals, so that the cold air can be more evenly distributed in every corner of the inner tank. This multi-point air supply method effectively avoids the local temperature difference that may be caused by single-point air supply, and further improves 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 design of the above technical solution enables the cold air to be more evenly diffused along the increasing number of air outlet slots after entering the air supply channel. The fewer air outlet slots near the air inlet help to form the initial cold air flow, while the increase in the number of air outlet slots away from the air inlet promotes further dispersion and mixing of the cold air, thereby forming a more uniform and stable temperature field inside the liner.

[0011] In addition, through the design of gradually increasing air outlet slots, the cold air can more effectively cover various areas of the inner tank during the flow process. Especially at the far end or corner of the inner tank, the increase in the number of air outlet slots ensures that these areas can also obtain sufficient cold air supply, thereby improving the overall air supply efficiency and temperature control effect.

[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 the 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, each air outlet slot in the air outlet module corresponds to at least one sub-channel.

[0015] In the above 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 controlled more accurately. By adjusting the size, shape or number of the sub-channels, the air flow rate of different air outlet slots 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 inside the liner.

[0016] Furthermore, the inner tank 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 smaller 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 design of the Z-shaped bottom plate not only effectively closes the bottom of the first and second enclosures, but also increases the structural strength of the liner body through its unique shape. The Z-shaped structure can provide additional support in the vertical and horizontal directions, making the liner body more stable and able to withstand greater pressure and impact. In addition, the structural design of the inner plate body also provides sufficient installation space for equipment such as compressors.

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

[0019] In the above technical solution, the design of the card slot and the top of the inner liner body ensures a tight connection between the extension part and the inner liner body, effectively preventing the penetration of air or moisture. In addition, the design of the card slot and the card connection makes the installation of the extension part and the inner liner body simple and quick. No complicated fixings or tools are required, and the installation can be completed by simply aligning the top of the inner liner body with the card slot and gently pushing it in.

[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 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 port enables the air inside the inner tank to form an effective circulation flow. The design of the drain port can timely discharge the condensed water formed in the inner tank body to prevent it from accumulating and possibly causing damage to the internal items.

[0024] The present invention 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 inner liner structure into the refrigerator and closely connecting it with the refrigeration system and the fan, on the one hand, the refrigeration capacity of the refrigerator can be significantly improved, and the cold air can be more evenly and efficiently distributed inside the inner liner, thereby achieving a fast and stable refrigeration effect. On the other hand, it can greatly facilitate the assembly of the refrigerator, wherein the assembly of the inner liner part only requires the inner liner body to be clipped onto the box surface frame, which is simple and convenient to operate, and can effectively improve assembly efficiency and reduce production costs.

DETAILED DESCRIPTION

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show 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 invention is as follows.

[0034] Please refer to Figure 1-Figure 3A liner structure comprises an liner body 1 with an opening at the top, and a box surface frame 2 arranged on the top of the liner body 1, the box surface frame 2 comprises 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] The frame 21, extension 22 and air outlet module 24 in the box face frame 2 of this embodiment are an integrated structure. This design 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 24 and the air duct cover plate 25 with the box face frame 2, the assembly process of the refrigerator liner is reduced. It is only necessary to splice the liner body 1 with the box face frame 2, 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 invention does not need to assemble an additional air outlet cover plate, 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 disposed at intervals 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 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 liner. In addition, 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 liner structure to adapt to various liner designs, and the best air supply effect can be achieved by adjusting the position and number of air outlet modules 24.

[0038] In this embodiment, each air outlet module 24 includes a plurality of air outlet slots 241 , each of which has 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 a direction away from the air inlet 23 .

[0039] The design of the above technical solution enables the cold air to be more evenly diffused along the gradually increasing number of air outlet slots 241 after entering the air supply channel. The number of air outlet slots 241 near the air inlet 23 is relatively small, which helps to form the initial cold air flow, and as it moves away from the air inlet 23, the increase in the number of air outlet slots 241 promotes further dispersion and mixing of the cold air, thereby forming a more uniform and stable temperature field inside the liner.

[0040] In addition, through the design of the gradually increasing air outlet slots 241, the cold air can more effectively cover various areas of the inner liner during the flow process. In particular, at the far end or corner of the inner liner, the increase in the number of air outlet slots 241 ensures that these areas can also obtain sufficient cold air supply, thereby improving the overall air supply efficiency and temperature control effect.

[0041] In this embodiment, a plurality of mutually parallel partitions 251 are arranged at intervals on the air duct cover plate 25, and the plurality of partitions 251 divide the air supply channel into a plurality of 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 current phenomena, 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 liner. Each sub-channel 252 undertakes a certain amount of air supply tasks. By reasonably 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 substantially the same, thereby forming a more uniform temperature field inside the 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 accurately controlled. By adjusting the size, shape or number of the sub-channels 252, fine adjustment of the air flow rate of different air outlet slots 241 can be achieved, and the air flow rate of each air outlet slot 241 can be ensured to be consistent, thereby meeting the specific temperature requirements of different areas inside the inner tank.

[0043] Please refer to Figure 4-Figure 5 In this embodiment, the inner tank 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 the height 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 design of the Z-shaped bottom plate 13 not only effectively closes the bottom of the first enclosure 11 and the second enclosure 12, but also increases the structural strength of the liner body 1 through its unique shape. The Z-shaped structure can provide additional support in the vertical and horizontal directions, making the liner body 1 more stable and able to withstand greater pressure and impact. In addition, the structural design of the inner plate body also provides sufficient installation space for equipment such as compressors.

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

[0046] The snap-fit ​​design of the card slot and the top of the liner body 1 in this embodiment ensures a tight connection between the extension 22 and the liner body 1, effectively preventing the penetration of air or moisture. In addition, the card slot and snap-fit ​​design make the installation of the extension 22 and the liner body 1 simple and quick. No complicated fixings or tools are required, and the installation can be completed by simply aligning the top of the liner body 1 with the card slot and gently pushing it in.

[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 bent portion 111 and the second bent 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, a return air port 131 and a drain port 132 are provided at the bottom of the inner tank body 1. The design of the return air port 131 enables the air inside the inner tank to form an effective circulation flow. In a refrigerated, frozen or humid environment, condensed water may be generated inside the inner tank. The design of the drain port 132 can discharge the condensed water from the inner tank in time to prevent it from accumulating and possibly causing damage to the internal items. At the same time, the presence of the drain port 132 also reduces the problem of bacterial growth caused by the accumulation of condensed 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 tank structure into the refrigerator and closely connecting it with the refrigeration system and the fan, on the one hand, the refrigeration capacity of the refrigerator can be significantly improved, and the cold air can be more evenly and efficiently distributed inside the inner tank, thereby achieving a fast and stable refrigeration effect. On the other hand, it can greatly facilitate the assembly of the refrigerator, wherein the assembly of the inner tank part only requires the inner tank body 1 to be snapped onto the box surface frame 2, which is simple and convenient to operate, and can effectively improve the assembly efficiency and reduce the production cost.
