Description

Technical Field

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

[0002] In the traditional and mature industrial field of freezer manufacturing, the typical structure of existing freezers mainly consists of two parts: the outer shell and the inner liner. The space between the bottom plate of the outer shell and the bottom of the inner liner needs to be filled with a foam layer. Due to its unique physical properties, the foam layer can effectively block heat transfer, providing good heat insulation for the freezer and ensuring that the freezer maintains a stable low-temperature environment to meet the needs of food refrigeration and freezing.

[0003] In existing technology, a flanged structure is installed along the edge of the base plate to facilitate the filling of the foam layer and prevent leakage of foam material during the filling process. However, in actual base plate assembly, the corners of the flanged edges become a thorny problem. Due to the complex shape of this area, extensive sealing with tape is required. This operation demands a high level of installation experience from the operator, and due to the inherent flexibility and adhesion of the tape, it is difficult to perfectly conform to the contours of the base plate, especially at irregular areas such as corners. This leads to gaps between the base plate and the tape. During subsequent foaming, material overflow is likely to occur at the corners of the base plate, and voids may appear at the corners, reducing the insulation performance of the corner area and severely affecting the quality of the freezer product.

[0004] To improve this situation, reinforcing irons are usually installed at the corners between adjacent flanges on the base plate to enhance angle support. However, when filling the foam layer, tape is still needed to seal the flanges and reinforcing irons. At this point, the problem of incomplete tape application and gaps remains prominent, leading to frequent defects such as overflow and empty space at the corners, posing a significant challenge to the stability of freezer production and product quality. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, the purpose of this utility model embodiment is to provide a freezer with flaps on each circumferential edge of the bottom plate. By adding a sealing plate, the corner gap between adjacent flaps is closed. When filling the foam layer, it is not necessary to seal the gap between adjacent flaps with tape, thereby reducing the use of tape, improving production efficiency, and reducing structural cost.

[0006] This utility model provides a freezer, including an inner liner, a foam layer, and a bottom plate. The bottom plate is located below the inner liner, and the foam layer fills the space between the bottom of the inner liner and the bottom plate.

[0007] The base plate has flaps along each circumferential edge, and corner gaps are formed between adjacent flaps;

[0008] A sealing plate is connected to the base plate or the flip plate. The sealing plate is located at the corner gap and is sealed to the adjacent flip plate. The flip plate and the sealing plate cooperate with the base plate to form a foam cavity that can be filled with a foam layer.

[0009] In the above technical solution, flaps are installed on each circumferential edge of the freezer bottom plate. By adding sealing plates connected to the bottom plate or flaps, and using the sealing plates to seal the corner gaps between adjacent flaps, the flaps, sealing plates, and bottom plate cooperate to form a closed foaming cavity. When filling the foaming cavity with foaming layer, it is not necessary to seal the gap between the flaps and sealing plates with tape, reducing the use of tape, improving assembly efficiency, avoiding the occurrence of foam leakage and cavitation, improving the quality and uniformity of the foaming layer, thereby enhancing the overall structural strength of the freezer, and the bottom plate structure has low cost.

[0010] In some embodiments, one end of the sealing plate is connected to one end of the flap extending along the edge, and the other end extends to seal the corner gap and then seals the flap adjacent to it.

[0011] In the above technical solution, by connecting one end of the sealing plate to one end of the flap extending along its edge, and then bending the sealing plate so that its other end extends to block the corner gap and seals with the adjacent flap, the connection between the sealing plate and the flap becomes more convenient. The operation of bending the sealing plate is relatively simple, requiring no complex tools or techniques, thus reducing processing difficulty and improving production efficiency.

[0012] In some embodiments, one end of the sealing plate is integrally connected to the flap, and the other end of the sealing plate is bent at the corner gap and then abuts against the inner wall of the adjacent flap to seal.

[0013] In the above technical solution, by integrally connecting one end of the sealing plate with the flap, the number of parts is reduced, avoiding the complex process of processing and assembling multiple parts separately, greatly simplifying the production process, improving production efficiency, and reducing quality problems caused by improper assembly. The other end of the sealing plate is bent at the corner gap and then abuts against the inner wall of the adjacent flap for sealing. This sealing method is simple to operate and does not require complex sealing structures or additional sealing parts. The tight contact between the two surfaces effectively achieves a seal, preventing foam material leakage, ensuring the quality and uniformity of the foam layer, and thus improving the heat insulation and thermal insulation performance and overall structural strength of the refrigerator.

[0014] In some embodiments, after the other end of the sealing plate is bent to seal the corner gap, it overlaps with the inner sidewall of the adjacent flap by a certain length along the edge direction of the bottom plate.

[0015] In the above technical solution, by overlapping the sealing plate by a certain length, the contact area between the inner walls of the sealing plate and the adjacent flap increases, thereby improving the sealing effect. On one hand, the larger overlapping contact area increases the friction and fit between the sealing plate and the inner walls of the adjacent flap, allowing them to bond more tightly together under the pressure of the foaming material during the foaming process, effectively preventing foam leakage. On the other hand, this design eliminates the need for complex sealing structures and additional sealing parts. By simply controlling the overlap length between the sealing plate and the flap, it simplifies the production process, reduces production costs, and improves production efficiency and product reliability while ensuring a good sealing effect.

[0016] In some embodiments, the flap is provided with an avoidance notch near the corner gap, the avoidance notch extending downward from the top of the flap and penetrating the bottom wall of the base plate;

[0017] The other end of the sealing plate extends to be flush with the edge of the clearance gap.

[0018] The above technical solution not only allows the other end of the sealing plate to overlap with the flap by a certain length, but also strengthens the edge of the gap.

[0019] In some embodiments, the top of the sealing plate is flush with the top of the flap, and the bottom end of the sealing plate abuts against the bottom wall of the base plate.

[0020] In the above technical solution, the top of the sealing plate is flush with the top of the flap, avoiding the problem of foam material overflowing at the top due to the height difference. From the perspective of structural stability, the flush top makes the sealing plate and the flap more coordinated in appearance and structure, enhancing the overall structural strength. The bottom end of the sealing plate abuts against the bottom plate, reducing the gap between the sealing plate and the bottom plate. Combined with the application of tape to close the gap between the sealing plate and the bottom plate, this prevents the foam material from leaking from the bottom. The two work together to form a complete sealing system, greatly improving the sealing performance of the freezer, ensuring that the foam layer can be fully and evenly filled at the bottom of the freezer, and improving the heat insulation and heat preservation effect of the freezer.

[0021] In some embodiments, the base plate includes a first plate and a second plate that are both horizontally arranged, and a vertical plate that is vertically connected between the first plate and the second plate, wherein the first plate is arranged higher than the second plate;

[0022] The vertical plate has a connecting plate along its edge, and the flap is located on the edges of the first plate and the second plate, and cooperates with the connecting plate and the sealing plate to form the foaming cavity.

[0023] In some embodiments, a receiving cavity for mounting a compressor is formed below the first plate, and the freezer further includes a reinforcing frame disposed in the receiving cavity, with the first plate supported on the top wall of the reinforcing frame.

[0024] In the above technical solution, by connecting a sealing plate to the flap, the corner gap between adjacent flaps is sealed by the sealing plate. It is not necessary to set reinforcements on the reinforcing frame and assemble the reinforcements at the corner gap. It is only necessary to support the first plate on the top wall of the reinforcing frame, which makes the assembly simple.

[0025] In some embodiments, the sidewalls of the reinforcing frame form a positioning and mounting structure; the freezer is provided with a surrounding panel that surrounds the bottom plate and the reinforcing frame, the inner wall of the surrounding panel having a positioning part, the positioning part being connected to the positioning and mounting structure.

[0026] In the above technical solution, the side wall of the reinforcing frame protrudes from the flap and the connecting plate to form the positioning and installation structure, so as to facilitate the positioning of the enclosure and the base plate structure during assembly and improve the assembly efficiency of the enclosure.

[0027] In some embodiments, the reinforcing frame includes a base and two vertically arranged mounting brackets, with the bottoms of the two mounting brackets respectively connected to the two ends of the base, and the top of the mounting brackets having a support platform, with the opposite edge portions of the first plate supported on the two support platforms.

[0028] In the above technical solution, regarding assembly convenience, the space formed between the two mounting brackets facilitates the assembly of the compressor, enabling it to be quickly and accurately installed in the designated position, thus improving production efficiency. The support platform at the top of the mounting brackets provides stable support for the first plate, ensuring its flatness and stability during installation, which is beneficial for the first plate to perform its intended function.

[0029] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0030] (1) The freezer base plate of this utility model is provided with flaps on each circumferential edge. By adding a sealing plate connected to the base plate or flap, and using the sealing plate to close the corner gap between adjacent flaps, the flap, sealing plate and base plate cooperate to form a closed foaming cavity. When filling the foaming cavity with foaming layer, it is not necessary to seal the gap between the flap and the sealing plate with tape, reducing the use of tape, improving assembly efficiency, avoiding the occurrence of foam leakage and cavitation, improving the quality and uniformity of the foaming layer, thereby enhancing the overall structural strength of the freezer, and the base plate structure has low cost.

[0031] (2) This utility model further improves the sealing effect by increasing the contact area between the sealing plate and the inner wall of the adjacent flap through this overlapping length setting. On the one hand, the larger overlapping contact area increases the friction and fit between the sealing plate and the inner wall of the adjacent flap, allowing them to bond more tightly together when subjected to the pressure of the foaming material during the foaming process, effectively preventing leakage of the foaming material. On the other hand, this setting does not require a complex sealing structure or additional sealing parts. By simply controlling the overlap length between the sealing plate and the flap, the sealing effect is ensured while simplifying the production process, reducing production costs, and improving production efficiency and product reliability.

[0047] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0049] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0050] like Figures 1 to 10As shown, an embodiment of this utility model provides a freezer. The freezer is a refrigeration device capable of maintaining a low internal temperature environment. It achieves cooling and maintains a stable low temperature by circulating refrigerant through a refrigeration system, absorbing heat. Widely used in commercial and household settings, the freezer effectively protects the quality of goods and provides reliable protection for the long-term preservation and convenient access to food, thanks to its precise temperature control and large-capacity storage capabilities.

[0051] This embodiment uses a horizontal freezer as an example. The freezer includes an inner liner, a foam layer, and an outer shell.

[0052] The outer shell includes a base plate structure located below the inner liner. The foam layer fills the space between the bottom of the inner liner and the base plate structure. The inner liner is the component inside the freezer used to hold items and comes into direct contact with them; it typically has a certain degree of low-temperature resistance and a smooth inner surface. The foam layer, formed by filling with foam material, serves to insulate and retain heat, and is a key structural component of the freezer in maintaining a low-temperature environment.

[0053] like Figures 1 to 2 As shown, the base plate structure includes a base plate 11, flaps 12, and a sealing plate 13. Each circumferential edge of the base plate 11 is provided with flaps 12, and corner gaps 15 are formed between adjacent flaps 12. Figure 1 A sealing plate 13 is not shown at a corner gap 15. A sealing plate 13 is connected to the base plate 11 or the flap 12, and the sealing plate 13 is located at the corner gap 15 to seal the corner gap 15. The sealing plate 13 is sealed to the adjacent flap 12, and the flap 12 and the sealing plate 13 cooperate with the base plate 11 to form a foam cavity that can be filled with a foam layer.

[0054] The freezer base plate 11 of this utility model has flaps 12 on each circumferential edge. By adding sealing plates 13 connected to the base plate 11 or flaps 12, and using the sealing plates 13 to seal the corner gaps 15 between adjacent flaps 12, the flaps 12, sealing plates 13 and base plate 11 cooperate to form a closed foaming cavity. When filling the foaming cavity with foaming layer, it is not necessary to seal the gap between flaps 12 and sealing plates 13 with tape, reducing the use of tape, improving assembly efficiency, avoiding the occurrence of foam leakage and cavitation, improving the quality and uniformity of the foaming layer, thereby enhancing the overall structural strength of the freezer, and the base plate structure has low cost.

[0055] The above scheme needs to be explained as follows: the foaming cavity is a concave cavity, and the bottom of the inner liner is located at the opening of the concave cavity. The bottom plate 11 includes a flat plate or a bent plate. The flip plate 12 and the sealing plate 13 are vertically arranged. The sealing plate 13 can be made of metal, rigid plastic, or composite material, etc. When the sealing plate 13 is attached to the bottom plate 11, the sealing plate 13 extends along the corner edge of the bottom plate 11. When the sealing plate 13 is connected to the flip plate 12, it can be an integral structure, welded, riveted, etc. The corner gap 15 is located at the corner of the bottom plate 11 on the horizontal plane.

[0056] In some embodiments, one end of the sealing plate 13 is connected to one end of the flap 12 extending along the edge, and the other end of the sealing plate 13 extends to seal the corner gap 15 and then is sealed to the adjacent flap 12.

[0057] This invention connects one end of the sealing plate 13 to one end of the flap 12 extending along its edge, and then bends the sealing plate 13 so that its other end extends to block the corner gap 15 and seals it with the adjacent flap 12, making the connection between the sealing plate 13 and the flap 12 more convenient. The operation of bending the sealing plate 13 is relatively simple, requiring no complex tools or techniques, reducing processing difficulty and improving production efficiency.

[0058] It should be noted that the sealing plate 13 abuts and is welded to the end face of the flap 12, or the sealing plate 13 overlaps and abuts, is welded, riveted or snapped to the inner or outer side wall of the adjacent flap 12.

[0059] The base plate 11 and the flap 12 are made of metal. The flap 12 is formed by folding upwards from each edge of the base plate 11. The sealing plate 13 is a curved plate-shaped component that seals the corner gap 15.

[0060] In some embodiments, one end of the sealing plate 13 is integrally connected to the flap 12, meaning that one end of the sealing plate 13 and the flap 12 are formed simultaneously during manufacturing using the same process, becoming an inseparable integral structure. This connection method avoids additional assembly steps and improves the overall integrity and stability of the structure. The other end of the sealing plate 13 is bent at the corner gap 15 and then abuts against the inner wall of the adjacent flap 12 for sealing. The tightness of the contact surfaces prevents leakage of materials such as foam, achieving a sealing effect. In this embodiment, the sealing connection between the flap 12 and the sealing plate 13 can be completed during the processing of the base plate structure.

[0061] This invention integrates one end of the sealing plate 13 with the flap 12, reducing the number of parts and avoiding the complex process of individually processing and assembling multiple parts. This greatly simplifies the production process, improves production efficiency, and reduces quality problems caused by improper assembly. The other end of the sealing plate 13 is bent at the corner gap 15 and then abuts against the inner wall of the adjacent flap 12 for sealing. This sealing method is simple to operate and does not require complex sealing structures or additional sealing parts. The tight contact between the two surfaces effectively achieves a seal, preventing foam material leakage, ensuring the quality and uniformity of the foam layer, and thus improving the heat insulation, thermal insulation performance, and overall structural strength of the refrigerator.

[0062] like Figures 3 to 5 As shown, after the other end of the sealing plate 13 is bent to seal the corner gap 15, it overlaps with the inner sidewall of the adjacent flap 12 along the edge extension direction of the bottom plate 11 for a certain length.

[0063] This invention, through this overlapping length arrangement, increases the contact area between the sealing plate 13 and the inner wall of the adjacent flap 12, thereby improving the sealing effect. On one hand, the larger overlapping contact area increases the friction and fit between the sealing plate 13 and the inner wall of the adjacent flap 12, allowing them to bond more tightly together during the foaming process, effectively preventing leakage of the foaming material. On the other hand, this arrangement eliminates the need for complex sealing structures and additional sealing parts; by simply controlling the overlap length between the sealing plate 13 and the flap 12, it simplifies the production process, reduces production costs, and improves production efficiency and product reliability while ensuring a good sealing effect.

[0064] like Figures 4 to 5 As shown, the sealing plate 13 includes a curved plate segment 131 and a straight plate segment 132. One end face of the curved plate segment 131 is connected to one end face of the flap 12, and the other end of the curved plate segment 131 is connected to one end of the straight plate segment 132. The other end of the straight plate segment 132 overlaps with the inner sidewall of the adjacent flap 12 by a certain length and abuts against it for sealing.

[0065] The flap 12 is provided with an avoidance notch 16 near the corner gap 15. The avoidance notch 16 extends downward from the top of the flap 12 and penetrates the bottom wall of the base plate 11. The other end of the sealing plate 13 extends to be flush with the edge of the avoidance notch 16, which not only allows the other end of the sealing plate 13 to overlap with the flap 12 by a certain length, but also strengthens the edge of the avoidance notch 16.

[0066] The top of the sealing plate 13 is flush with the top of the flip plate 12, and the bottom of the sealing plate 13 abuts against the bottom wall of the base plate 11. When assembling the base plate structure, it is only necessary to seal the area between the bottom of the sealing plate 13 and the base plate 11 with tape, without the need to apply tape between the sealing plate 13 and the flip plate 12.

[0067] like Figure 3 As shown, the base plate 11 includes a vertical plate 112, a first plate 111 and a second plate 113, both horizontally arranged. The first plate 111 is positioned higher than the second plate 113, and the vertical plate 112 is vertically connected between the first plate 111 and the second plate 113.

[0068] The vertical plate 112 has a connecting plate 14 along its edge. The flap 12 is located on the edge of the first plate 111 and the second plate 113. The bottom plate 11, the connecting plate 14, the flap 12, and the sealing plate 13 cooperate to form the foaming cavity.

[0069] Since the flap 12 on the second plate 113, the connecting plate 14 on the vertical plate 112, and the flap 12 on the first plate 111 are located on the same vertical plane along the bending direction of the base plate 11, there are no corners on the horizontal plane. Therefore, a complete seal is not required between the adjacent ends of the connecting plate 14 and the flap 12.

[0070] The outer casing also includes a surrounding panel (not shown in the figure). The surrounding panel is fitted around the outer periphery of the base plate structure and is sealed to the flap 12 and the connecting plate 14. The seal is achieved by the surrounding panel engaging with the flap 12 and the connecting plate 14.

[0071] The lower end face of the connecting plate 14 abuts against the end face of the flap 12 on the first plate 111.

[0072] like Figures 6 to 10 As shown, a receiving cavity for mounting the compressor is formed below the first plate 111. The freezer also includes a reinforcing frame 2. The reinforcing frame 2 is disposed in the receiving cavity, and the first plate 111 is supported on the top wall of the reinforcing frame 2.

[0073] This utility model, by connecting a sealing plate 13 to the flap 12, uses the sealing plate 13 to close the corner gap 15 between adjacent flaps 12, eliminating the need to install reinforcing members on the reinforcing frame 2 and assemble the reinforcing members at the corner gap 15. It only requires supporting the first plate 111 on the top wall of the reinforcing frame 2, making assembly simple.

[0074] The sidewalls of the reinforcing frame 2 form a positioning and mounting structure. The enclosure panel surrounds the reinforcing frame 2 and the base plate structure. The inner wall of the enclosure panel has a positioning part, which is connected to the positioning and mounting structure.

[0075] Preferably, the sidewall of the reinforcing frame 2 protrudes from the flap 12 and the connecting plate 14 to form the positioning and installation structure, so as to facilitate the positioning of the enclosure and the base plate structure during assembly and improve the assembly efficiency of the enclosure.

[0076] like Figures 8 to 10 As shown, the reinforcing frame 2 includes a base 22 and two vertically arranged mounting brackets 21. The two ends of the base 22 are respectively connected to the bottoms of the two mounting brackets 21, forming a receiving space between the two mounting brackets 21 to facilitate compressor assembly. The top of each mounting bracket 21 has a support platform 2131, and the opposite edges of the first plate 111 are supported on the two support platforms 2131.

[0077] The support platform 2131 protrudes from the outer wall of the flap 12. Part of the structure of the support platform 2131 supports the first plate 111, and part of the structure protrudes from the outer wall of the flap 12 and serves a positioning function.

[0078] The mounting bracket 21 includes a bottom crossbeam 211, a top crossbeam 213, and a vertical beam 212.

[0079] Specifically, the top crossbeam 213 and the bottom crossbeam 211 are spaced apart vertically, and two vertical beams 212 are respectively connected between the top crossbeam 213 and the bottom crossbeam 211. The base 22 has a certain extension length and extends along the connection between the vertical plate 112 and the second plate 113. The vertical beam 212 includes a first vertical beam and a second vertical beam, and the first vertical beams of the two mounting brackets 21 respectively abut against the vertical plate 112.

[0080] The edge portion of the top crossbeam 213 and the outer side wall of the vertical beam 212 protrude from the flap 12. The bottom crossbeam 211 protrudes laterally from the first vertical beam and abuts against the outer side wall of the flap 12 on the second plate 113.

[0081] Preferably, the vertical beam 212 is a bent beam. More preferably, the vertical beam 212 is an L-shaped beam.

[0082] The mounting bracket 21 is provided with a vertically extending clearance opening, which is vertically opposite to the clearance notch 16 on the base plate structure. The clearance notch 16 and the clearance opening are used to avoid the vertically extending connection of the enclosure panel.
