Description

Technical Field

[0001] The invention relates to the field of refrigeration equipment, and in particular to a refrigerator with a novel waterproof structure at the bottom of an inner tank. Background Art

[0002] In the field of refrigeration equipment, freezers, as common storage equipment, are widely used in many industries such as food, medical treatment, and scientific research. The performance and stability of freezers are directly related to the quality and safety of stored items. However, the traditional freezer liner design often has the problem of insufficient waterproof performance, especially at the bottom of the liner. Due to the limitations of the structural design, it is easy to become a weak link for moisture intrusion. Once moisture seeps out of the bottom of the liner, it may not only cause the humidity inside the freezer to increase, affecting the dryness and shelf life of the stored items, but may also damage the freezer's refrigeration system and electrical components, causing safety hazards.

[0003] In order to solve the above problems, existing refrigerators usually apply glue at the connection between the inner tank bottom plate and the inner tank side plate, but the glue is prone to yellowing and the glue application is uneven and unsightly. At the same time, the glue application process is increased, resulting in reduced production efficiency. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a refrigerator with a novel waterproof structure at the bottom of an inner tank.

[0005] A refrigerator with a novel waterproof structure at the bottom of an inner liner, the refrigerator comprises an inner liner, the inner liner comprises a bottom plate, a back plate and two side plates, upper flange plates are arranged on both sides and the back of the bottom plate, and the bottoms of the side plates and the back plate are respectively connected to the upper flange plates.

[0006] More specifically, in the above technical solution, a folded edge is provided on the outer side of the bottom of the side panel, the folded edge is connected to the inner side of the upper flange panel, the edge of the folded edge is a knife edge, and the knife edge is located in the foaming layer.

[0007] To be more specific, in the above technical solution, the upper flange plate at the rear of the base plate is provided with a first rear bent plate, and the bottom of the rear plate is provided with a second rear bent plate, the first rear bent plate and the second rear bent plate are connected, and the edges of the first rear bent plate and the second rear bent plate are knife edges, and the knife edges are located in the foaming layer.

[0008] More specifically, in the above technical solution, the plate material of the inner liner is a pre-coated plate material.

[0009] More specifically, in the above technical solution, the refrigerator further comprises a box frame, the box frame is located at the front side of the inner container, and a light strip mounting member is connected between the box frame and the inner container.

[0010] More specifically, in the above technical solution, a buckle groove is provided on one side of the light strip mounting piece, the front portion of the side panel is disposed in the buckle groove, and the other side of the light strip mounting piece is buckled and connected to the box frame.

[0011] More specifically, in the above technical solution, a drainage groove is provided at the rear of the bottom plate, and a drainage hole is provided in the drainage groove.

[0012] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0013] 1. The present invention forms a complete waterproof barrier by arranging upper flange plates on both sides and the rear of the bottom plate of the inner tank and connecting them with the bottom of the side plate and the rear plate, effectively preventing moisture from invading from the bottom of the inner tank, and significantly improving the waterproof performance of the refrigerator. In particular, the overlapping edge design at the bottom of the side plate and the first and second rear bent plates of the rear plate cleverly hide the blade in the foaming layer, which not only avoids the rust problem caused by the blade being exposed to the outside, but also further enhances the waterproof effect.

[0014] 2. The existing light troughs of refrigerators are all arranged on the side panels of the inner tank, and the bottom plate of the inner tank cannot make a smooth upper flange structure. However, the present invention adjusts the design of the inner tank and the box frame, moves the light trough to the box frame, so that the bottom of the inner tank can make a smooth upper flange structure, which not only meets the waterproof requirements, but also ensures the aesthetics of the refrigerator.

[0025] References to "one embodiment" or "some embodiments" etc. described in the specification of the present invention mean that one or more embodiments of the present invention include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0026] In the prior art, the bottom sides and rear of the inner liner usually need to be glued for waterproofing, which not only increases the production cost, but also may cause aesthetic problems such as yellowing of the glue and uneven glue application. However, the present invention achieves a good waterproof effect without glue application through the design of the upper flange plate 3 and the overlapped edge 4, thereby simplifying the production process and reducing the cost.

[0027] See also Figure 2 The present application discloses a refrigerator having a novel waterproof structure at the bottom of an inner liner, the refrigerator comprising an inner liner, the inner liner comprising a bottom plate 101, a rear plate 102 and two side plates 103, upper flange plates 3 are provided on both sides and the rear of the bottom plate 101, the side plates 103 and the bottom of the rear plate 102 are respectively connected to the upper flange plates 3.

[0028] Upper flange plates 3 are provided on both sides and the rear of the bottom plate 101, which not only enhance the edge strength of the bottom plate 101 to prevent deformation or damage caused by long-term load-bearing or external force impact, but also construct a waterproof barrier; the upper flange plates 3 are like a solid embankment, which effectively prevents the infiltration of condensation water or other liquids, thereby avoiding moisture, corrosion and other problems inside the box, and extending the service life of the refrigerator.

[0029] In some embodiments, Figure 1 and Figure 3 As shown, a folding edge 4 is provided on the outer side of the bottom of the side panel 103, and the folding edge 4 is connected to the inner side of the upper flange plate 3. The edge of the folding edge 4 is a cutting edge 5, and the cutting edge 5 is located in the foaming layer; the cutting edge 5 is a cut edge punched out after sheet metal processing.

[0030] The overlapped edge 4 is tightly connected to the inner side of the upper flange plate 3 to form a stable connection structure. The blade 5 of the overlapped edge 4 is hidden in the foaming layer to avoid direct exposure of the blade 5 to the external environment, thereby effectively preventing the corrosion and oxidation of the blade 5 by water vapor, thereby avoiding the occurrence of rust problems.

[0031] The blade 5 is bent into the foam layer through the overlapped edge 4, which not only solves the rust problem, but also brings many other advantages. First, because the blade 5 is hidden in the foam layer, even if it is slightly rusted after long-term use, it will not affect the appearance of the refrigerator, and the high-end texture of the product is maintained. Secondly, the requirements for the material of the plate are reduced. In the case of not adopting the overlapped edge 4 design, in order to avoid the blade 5 from rusting, it is usually necessary to use a rust-free roll-coated aluminum plate. However, the cost of the roll-coated aluminum plate is relatively high and may not be necessary in some application scenarios. The design in this embodiment, even if a lower-cost iron plate is used, can effectively avoid the problem of rust on the blade 5 through the protection of the overlapped edge 4 and the foaming layer, thereby reducing production costs.

[0032] In some embodiments, Figure 1As shown, the upper flange plate 3 at the rear of the base plate 101 is provided with a first rear bending plate 6, and the bottom of the rear plate 102 is provided with a second rear bending plate 7, the first rear bending plate 6 and the second rear bending plate 7 are connected, and the edges of the first rear bending plate 6 and the second rear bending plate 7 are cutting edges 5, and the cutting edges 5 are located in the foaming layer.

[0033] The upper flange plate 3 at the rear of the bottom plate 101 is provided with a first rear bent plate 6, and the bottom of the rear plate 102 is provided with a second rear bent plate 7. These two bent plates are combined with each other through a precise connection method to form a strong and waterproof barrier at the rear of the refrigerator liner.

[0034] The edges of the first rear bent plate 6 and the second rear bent plate 7 are both provided with a knife edge 5, which is embedded in the foam layer, which not only further enhances the stability of the inner liner structure, but also greatly improves the waterproof performance. Since the knife edge 5 is hidden in the foam layer, it completely avoids direct contact with external water vapor, thereby effectively preventing rust caused by oxidation and simplifying the maintenance process of the refrigerator. Since the knife edge 5 is hidden inside, users do not need to worry about damage or contamination to these sensitive parts during daily use, thereby reducing maintenance costs and difficulties.

[0035] In some embodiments, the sheet material of the inner liner is a pre-coated sheet material.

[0036] Existing refrigerator inner panels are usually made of roll-coated aluminum plates. Due to the design of the folded edge 4 and the rear bent plate of the present application, the blade 5 is located in the foaming layer, which ultimately makes the inner liner plate material of this scheme pre-coated, which can reduce costs. If roll-coated aluminum plates are used, although they will not rust, the cost of roll-coated aluminum plates is relatively high.

[0037] On the other hand, due to the presence of the upper flange plate 3, the edge of the inner liner is better protected, reducing the risk of rust caused by water vapor erosion, making the inner liner more flexible in material selection and no longer limited to those high-cost rust-proof materials, and pre-coated plate materials can be used.

[0038] In some embodiments, Figure 4 As shown, the refrigerator further includes a box frame 8, which is located at the front side of the inner container, and a light strip mounting member 9 is connected between the box frame 8 and the inner container.

[0039] The existing refrigerator light trough is usually set on the side plate 103 of the inner plate. When the inner tank side plate 103 has a light trough, the bottom of the inner tank bottom plate 101 cannot make a flat upward flange structure. If the side plate 103 is provided with a light trough, the upper flange plate 3 connecting the bottom plate 101 and the side plate 103 needs to have several more upper flanges, and the above structure cannot be made.

[0040] As mentioned above, providing the upper flange plate 3 on the inner liner bottom plate 101 is an effective means to improve the waterproof performance. Since there are no light grooves on both sides of the inner liner, the upper flange plate 3 can extend continuously and smoothly to the side of the inner liner to form a complete waterproof barrier. The processing is simple and can effectively prevent the infiltration of condensed water or other liquids.

[0041] In some embodiments, Figure 4 As shown, a buckle groove 10 is provided on one side of the light strip mounting member 9 , the front portion of the side panel 103 is disposed in the buckle groove 10 , and the other side of the light strip mounting member 9 is buckled and connected to the box frame 8 .

[0042] The snap-on connection design allows the light strip mounting piece 9 to be quickly and easily fixed to the side panel 103 and the box frame 8 without the use of additional screws or other fasteners, thereby simplifying the installation process, reducing installation costs, and making subsequent disassembly and replacement work easier, thereby improving maintenance efficiency.

[0043] The cooperation between the snap groove 10 and the front of the side panel 103, as well as the snap connection between the light strip mounting piece 9 and the box frame 8, together form a stable mounting structure, which not only ensures the firmness of the light strip mounting piece 9 and prevents it from loosening or falling off during use, but also improves the overall structural stability of the refrigerator.

[0044] In some embodiments, Figure 2 As shown, a drainage groove 2 is provided at the rear of the bottom plate 101, and drainage holes are provided in the drainage groove 2.

[0045] The design of the drain groove 2 provides a clear drainage path, allowing condensed water or other liquids to quickly gather and flow to the drain hole, greatly speeding up the drainage speed and reducing the residence time of accumulated water at the bottom of the inner tank, thereby reducing the risk of corrosion and mold caused by accumulated water.

[0046] Although the drainage groove 2 itself has a certain drainage capacity, it cannot fully guarantee the waterproof effect (such as a large amount of condensed water or clogging of the drainage hole). The waterproof structure of the present application, such as the upper flange plate 3, combined with the drainage groove 2, forms a multi-level waterproof system. This design not only enhances the reliability of waterproofing, but also improves the overall durability of the refrigerator.

[0047] In addition, the setting of the drainage groove 2 usually needs to consider the spatial layout and the placement of items inside the inner tank. The waterproof structure of the present application optimizes the structural design of the inner tank without affecting the drainage function, making the internal space more reasonable and efficient, providing users with a larger storage space, and improving the practicality of the refrigerator.

[0048] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
