Description

Technical Field

[0001] The invention relates to the field of refrigerators, and in particular to a refrigerator box liner structure. Background Art

[0002] The assembly of the horizontal freezer liner is a key link in the manufacturing process of the freezer, which directly affects the insulation effect and service life of the freezer. When assembling the box liner in the prior art, the two panels and the bottom plate are usually spliced ​​together first, and then the connection between the bottom plate and the panel is wrapped and bonded with tape to fix. However, in the actual assembly process, a portion of the edge of the bottom plate will protrude, resulting in a 90-degree angle at the connection between the panel and the bottom plate, making it difficult for the tape to fit completely when wrapped and easily forming a gap. This will cause the box body to be foamed. Due to the gap between the tape and the corner, the gap cannot be filled with foaming liquid, which will easily lead to delamination at the corner and ripples inside the liner, affecting the appearance and quality of the product. Summary of the invention

[0003] In view of this, the present invention provides a refrigerator box liner structure that can reduce the use of tape and facilitate assembly in order to solve the above technical problems.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A refrigerator box liner structure comprises a first enclosure and a second enclosure with flush tops, and a Z-shaped bottom plate, wherein the height of the second enclosure is less than that of the first enclosure, and the Z-shaped bottom plate is used to close the bottoms of the first enclosure and the second enclosure; a first card slot is provided at the bottom outer edge of the first enclosure, and a second card slot is provided at the bottom outer edge of the second enclosure, the notches of the first card slot and the second card slot are both downward, and a folded edge is provided at the edge of the Z-shaped bottom plate, and the folded edge can be snapped into the first card slot and the second card slot.

[0006] In the above technical solution, the folded edge of the Z-shaped bottom plate is fixed to the card slot at the bottom of the first and second enclosures, thereby simplifying the installation process and eliminating the need for additional tape for fixing. On the one hand, the assembly efficiency is greatly improved, and it is also convenient for later disassembly and maintenance, thereby reducing maintenance costs. On the other hand, since there is no need to stick tape, there is no gap formed by sticking tape at the connection between the first or second enclosure and the Z-shaped bottom plate, and the foam liquid can also completely fill and support the liner, thereby eliminating delamination and corrugation, and improving product quality and aesthetics.

[0007] Furthermore, the first enclosure is a plate-like structure bent twice in the same direction, a first boss is provided on the bottom outer edge of the first enclosure, the first boss surrounds and fits the first enclosure, and the first slot is provided at the bottom of the first boss.

[0008] In the above technical solution, the first enclosure is designed to be bent twice in the same direction, which not only increases its own rigidity but also forms a stable supporting structure. This structural design can effectively resist external impact and extrusion and prevent deformation, thereby improving the durability and service life of the overall product. In addition, the first boss facilitates the design of the first slot, so that the folded edge of the Z-shaped bottom plate that matches it can be easily and quickly inserted and fixed without the need for additional fasteners or complicated operating steps, which not only improves production efficiency but also reduces assembly costs.

[0009] Furthermore, the second enclosure is a plate-like structure bent twice in the same direction, a second boss is provided on the bottom outer edge of the second enclosure, the second boss surrounds and fits the second enclosure, and the second slot is provided at the bottom of the second boss.

[0010] In the above technical solution, the structural design of the second enclosure is the same as that of the first enclosure. When the first enclosure and the second enclosure are designed to be plate-like structures bent twice in the same direction and each is equipped with a surrounding and fitting boss, the two can form a detachable structure with openings at both ends after assembly. At the same time, the first boss and the second boss can also effectively increase the structural strength of the inner liner and improve the overall load-bearing capacity and anti-deformation ability.

[0011] 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.

[0012] 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.

[0013] Furthermore, a first flange is provided at the top edge of the first enclosure, and a second flange is provided at the top edge of the second enclosure.

[0014] In the above technical solution, the first flange and the second flange can provide an additional protective layer for the top of the product, which can effectively prevent the top from being directly impacted or scratched, thereby increasing the service life of the product. On the other hand, it can facilitate assembly with the box surface frame. By providing grooves matching the first flange and the second flange on the box surface frame, the inner container can be clamped on the box surface frame through the first flange and the second flange, and no tape is required for fixing, so the assembly is convenient and quick.

[0015] Furthermore, the Z-shaped base plate includes a first plate body and a second plate body that are parallel and staggered, and a vertical plate body for connecting the first plate body and the second plate body, the folded edge on the first plate body is clamped in the first clamping groove, and the folded edge on the second plate body is clamped in the second clamping groove.

[0016] In the above technical solution, the design of the Z-shaped bottom plate greatly enhances the overall rigidity and load-bearing capacity of the bottom plate. The vertical plate body, as a supporting structure, effectively disperses the pressure from the upper enclosure, while the first plate body and the second plate body arranged in a staggered manner provide additional stability and anti-deformation ability, making the entire refrigerator box liner structure more solid and durable. In addition, the first plate body and the second plate body arranged in a staggered manner not only enhance the structural strength, but also cleverly utilize the space, so that the space under the bottom plate is more effectively utilized.

[0017] Furthermore, the first plate body is provided with a drainage hole.

[0018] In the above technical solution, the design of the drainage hole can ensure that during the use of the refrigerator, any accumulated water generated during condensation, thawing or cleaning can be quickly discharged through the drainage hole, effectively preventing the accumulation of accumulated water on the bottom plate, thereby avoiding affecting the sanitary conditions inside the refrigerator and causing contamination or damage to the stored food.

[0019] Furthermore, the first card slot and the second card slot are both "Ω"-shaped, the thickness of the folded edge is greater than the openings of the first card slot and the second card slot, and the folded edge is inserted into the first card slot and the second card slot by extrusion.

[0020] In the above technical solution, the design of the "Ω"-shaped slot provides a larger contact area and a more stable snap-on structure for the folded edge. Since the thickness of the folded edge is greater than the opening of the slot, when the folded edge is squeezed into the slot, a tight, almost seamless connection is formed, thereby greatly enhancing the stability of the connection between the bottom plate and the enclosure, and it is not easy to loosen or fall off even when subjected to external impact or vibration.

[0021] Furthermore, the folded edge and the Z-shaped bottom plate are an integrated structure.

[0022] In the above technical solution, the folded edge and the Z-shaped bottom plate adopt an integrated structure, that is, there are no additional connectors or seams between them, thereby eliminating potential weaknesses caused by loose connectors or stress concentration at the seams, thereby significantly enhancing the overall strength and stability of the entire structure.

DETAILED DESCRIPTION

[0029] 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.

[0030] Please refer to Figure 1-Figure 5 , a preferred embodiment of the present invention is as follows.

[0031] A refrigerator box liner structure includes a first enclosure 1 and a second enclosure 2 with flush tops, and a Z-shaped bottom plate 3, wherein the height of the second enclosure 2 is less than that of the first enclosure 1, and the Z-shaped bottom plate is used to close the bottoms of the first enclosure 1 and the second enclosure 2, so that there is a certain space under the second enclosure 2, which is convenient for placing equipment such as a compressor; a first card slot 12 is provided at the bottom outer edge of the first enclosure 1, and a second card slot 22 is provided at the bottom outer edge of the second enclosure 2, and the notches of the first card slot 12 and the second card slot 22 are both facing downward, and a folded edge 34 is provided at the edge of the Z-shaped bottom plate 3, and the folded edge 34 can be snapped into the first card slot 12 and the second card slot 22.

[0032] In this embodiment, the folded edge 34 of the Z-shaped bottom plate 3 is fixed to the card slots at the bottom of the first enclosure 1 and the second enclosure 2, thereby simplifying the installation process. No additional tape is required for fixing. On the one hand, the assembly efficiency is greatly improved, and it is also convenient for later disassembly and maintenance, thereby reducing maintenance costs. On the other hand, since there is no need to stick tape, there is no gap formed by sticking tape at the connection between the first enclosure 1 or the second enclosure 2 and the Z-shaped bottom plate 3, and the foam liquid can completely fill and support the inner liner, thereby eliminating delamination and corrugation, and improving product quality and aesthetics. In addition, since a simple snap-on structure is used instead of a complex connection method, the material consumption and labor costs in the production process are reduced, while the production efficiency is improved, thereby achieving effective cost control.

[0033] In this embodiment, the first enclosure 1 is a plate-like structure bent twice in the same direction. A first boss 11 is provided at the bottom outer edge of the first enclosure 1. The first boss 11 surrounds and fits the first enclosure 1, and a first slot 12 is provided at the bottom of the first boss 11.

[0034] The first enclosure 1 of this embodiment is designed to be bent twice in the same direction, which not only increases its own rigidity, but also forms a stable supporting structure. This structural design can effectively resist external impact and extrusion, prevent deformation, and thus improve the durability and service life of the overall product. In addition, the first boss 11 facilitates the design of the first slot 12, so that the folded edge 34 of the Z-shaped bottom plate 3 matched therewith can be conveniently and quickly inserted and fixed without the need for additional fasteners or complicated operating steps, which not only improves production efficiency but also reduces assembly costs.

[0035] Similarly, the second enclosure 2 is a plate-like structure bent twice in the same direction, and a second boss 21 is provided at the outer edge of the bottom of the second enclosure 2. The second boss 21 surrounds and fits the second enclosure 2, and the second slot 22 is provided at the bottom of the second boss 21. The first enclosure 1 and the second enclosure 2 are both "U"-shaped structures as a whole, and the two can be spliced ​​into a box structure with both ends open.

[0036] The structural design of the second enclosure 2 is the same as that of the first enclosure 1. When the first enclosure 1 and the second enclosure 2 are designed to be plate-like structures bent twice in the same direction and each is equipped with a surrounding and fitting boss, the two can form a detachable structure with openings at both ends after assembly. At the same time, the first boss 11 and the second boss 21 can also effectively increase the structural strength of the inner liner and improve the overall load-bearing capacity and anti-deformation ability.

[0037] The first boss 11 and the second boss 21 extend along the bottom edges of the first enclosure 1 and the second enclosure 2 respectively, that is, the lengths of the first boss 11 and the second boss 21 are the same as the bottom circumferences of the first enclosure 1 and the second enclosure 2 .

[0038] In this embodiment, the connecting ends of the first enclosure 1 and the second enclosure 2 are respectively provided with a first bending portion 13 and a second bending portion 23 folded in opposite directions, and the first bending portion 13 and the second bending portion 23 can be interlocked.

[0039] The design of the first bent portion 13 and the second bent portion 23 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.

[0040] In this embodiment, the top edge of the first enclosure 1 is provided with a first flange 14, and the top edge of the second enclosure 2 is provided with a second flange 24. The first enclosure 1 and the second enclosure 2 are both plate-like structures with three sides, so the first flange 14 and the second flange 24 are both provided with three corresponding to the three sides.

[0041] The first flange 14 and the second flange 24 can provide an additional protective layer for the top of the product, effectively preventing the top from being directly impacted or scratched, and improving the service life of the product. On the other hand, it can facilitate assembly with the box surface frame. By providing grooves matching the first flange 14 and the second flange 24 on the box surface frame, the inner container can be clamped on the box surface frame through the first flange 14 and the second flange 24, and no tape is required for fixing, which makes assembly convenient and quick.

[0042] In this embodiment, the Z-shaped base plate 3 includes a first plate body 31 and a second plate body 32 that are parallel and staggered, and a vertical plate body 33 for connecting the first plate body 31 and the second plate body 32. The folded edge 34 on the first plate body 31 is clamped in the first clamping groove 12, and the folded edge 34 on the second plate body 32 is clamped in the second clamping groove 22.

[0043] The design of the Z-shaped bottom plate 3 greatly enhances the overall rigidity and load-bearing capacity of the bottom plate. The vertical plate 33, as a supporting structure, effectively disperses the pressure from the upper enclosure, while the first plate 31 and the second plate 32, which are arranged in a staggered manner, provide additional stability and anti-deformation ability, making the entire refrigerator box liner structure more solid and durable. In addition, the first plate 31 and the second plate 32, which are arranged in a staggered manner, not only enhance the structural strength, but also cleverly utilize the space, so that the space under the bottom plate is more effectively utilized.

[0044] In this embodiment, a drainage hole 35 is provided on the first plate 31. The design of the drainage hole 35 can ensure that any accumulated water generated during condensation, thawing or cleaning of the refrigerator can be quickly discharged through the drainage hole 35 during use, effectively preventing the accumulation of accumulated water on the bottom plate, thereby avoiding affecting the sanitary conditions in the refrigerator and causing contamination or damage to the stored food.

[0045] In this embodiment, the first card slot 12 and the second card slot 22 are both "Ω"-shaped, the thickness of the folded edge 34 is greater than the openings of the first card slot 12 and the second card slot 22, and the folded edge 34 is inserted into the first card slot 12 and the second card slot 22 by extrusion.

[0046] The design of the "Ω"-shaped slot provides a larger contact area and a more stable snap-on structure for the folded edge 34. Since the thickness of the folded edge 34 is greater than the opening of the slot, when the folded edge 34 is squeezed into the slot, a tight, almost seamless connection is formed, thereby greatly enhancing the connection stability between the bottom plate and the enclosure, and it is not easy to loosen or fall off even when subjected to external impact or vibration.

[0047] It should be noted that the folded edge 34 of this embodiment is an integral structure with the Z-shaped bottom plate 3. The folded edge 34 and the Z-shaped bottom plate 3 are an integral structure, that is, there are no additional connectors or seams between them, thereby eliminating potential weaknesses caused by loose connectors or stress concentration at the seams, thereby significantly enhancing the overall strength and stability of the entire structure.
