Abstract
Description
Technical Field
[0001] The present application relates to the technical field of household appliances, and more specifically to a bottom plate assembly for a refrigerator and a refrigerator. Background Art
[0002] There are generally three types of materials for refrigerator bottom plates: galvanized steel, PVC and PP hollow plates. Among them, galvanized steel is known for its high strength, corrosion resistance and excellent processing performance, but its high price increases production costs, so it is not suitable for all types of refrigerator products. Although PP hollow plates have the advantages of light weight and low cost, their flame retardant grade is only V2, which is relatively low and cannot meet the safety performance requirements of modern refrigerators. Therefore, they are gradually being eliminated by the market.
[0003] In contrast, PVC material has the characteristic of self-extinguishing when away from fire. Through formula optimization, it can reach the flame retardant level of 5V, which has higher safety performance. At present, refrigerator products mainly use the combination of PVC and galvanized steel plate. This combination bottom plate is usually composed of multiple sub-components, including left and right PVC side panels, PVC large surface, left and right sheet metal brackets and sheet metal cross beams.
[0004] In the combined bottom plate of PVC and galvanized steel plate, the assembly process is cumbersome due to the large number of sub-components. The sub-components need to go through multiple welding and riveting processes before they can be assembled together, which not only increases the production cost but also reduces the production efficiency. In addition, since there are gaps at the joints of the sub-components, in order to ensure the sealing inside the refrigerator, additional sponge parts need to be added for sealing. However, this treatment method not only increases the material cost, but also may cause safety hazards such as foaming and leakage due to aging or falling off of the sponge parts.

[0027] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the embodiments of the present invention will be more comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the implementation of the embodiments of the present invention.
[0028] There are generally three kinds of materials for existing refrigerator bottom plates: galvanized steel plates, PVC and PP hollow plates. Among them, galvanized steel plates have high production costs. Although PP hollow plates have the advantages of light weight and low cost, their flame retardant grade is only V2, which is relatively low. In contrast, PVC material has the characteristics of self-extinguishing when away from fire. Through formula optimization, it can reach a flame retardant grade of 5V, which has higher safety performance. At present, refrigerator products mainly adopt the combination of PVC and galvanized steel plates. However, in the combined bottom plate of PVC and galvanized steel plates, the assembly process is cumbersome due to the large number of sub-components. Each sub-component needs to go through multiple welding and riveting processes before it can be assembled together, which not only increases the production cost, but also reduces the production efficiency. In addition, since there is a gap at the joint of the sub-components, in order to ensure the sealing inside the refrigerator, additional sponge parts need to be added for sealing. However, this treatment method not only increases the material cost, but also may cause safety hazards such as foaming and leakage due to aging or shedding of sponge parts.
[0029] In order to solve the above problems, the first aspect of the embodiment of the present application provides a bottom plate assembly for a refrigerator, referring to Figure 1 As shown, the refrigerator bottom plate assembly in this embodiment mainly includes two parts: a PVC part 10 and a bracket 20. The PVC part 10, as the main part of the bottom plate, adopts an integrated molding structure based on the vacuum forming process, which not only simplifies the production process, but also greatly improves the integrity and stability of the product.
[0030] The specific structure of the PVC part 10 includes a first panel 11, a second panel 12, a third panel 13 and a fourth panel 14. The bracket 20 includes a left sheet metal bracket 21 and a right sheet metal bracket 22. Among them, one side of the second panel 12 is vertically fixed to one side of the third panel 13, forming a stable right-angle structure. The left sheet metal bracket 21 and the right sheet metal bracket 22 are respectively fixed at both ends of the second panel 12 and the third panel 13, and are symmetrically arranged on the left and right sides, which not only enhances the load-bearing capacity of the bottom plate assembly, but also provides stable support for other components inside the refrigerator.
[0031] The first panel 11 is located on a side of the second panel 12 away from the third panel 13 and is fixedly connected thereto. The first panel 11 extends in a direction away from the bracket 20, providing installation space for other components at the bottom of the refrigerator. Similarly, the fourth panel 14 is located on a side of the third panel 13 away from the second panel 12 and is fixedly connected thereto, and also extends in a direction away from the bracket 20, further expanding the installation area of the bottom plate assembly.
[0032] The PVC member 10 in the refrigerator bottom plate assembly of the present application is integrally formed by the vacuum forming process, which greatly reduces the number of sub-parts, simplifies the assembly process, and reduces the production cost. The left sheet metal bracket 21 and the right sheet metal bracket 2122 are connected to the second plate surface 12 and the third plate surface 13 of the PVC member 10 by a simple fixing method (such as bolt connection or welding), without multiple welding and riveting processes, thereby improving production efficiency.
[0033] And because the PVC part 10 adopts an integrated molding structure, the gaps at the joints of the sub-parts are greatly reduced, and there is no need to add additional sponge parts for sealing. Even if there are small gaps, the sealing can be ensured by adjusting the size and shape of the PVC part 10. The PVC material has the characteristic of self-extinguishing when away from fire, and can reach a flame retardant level of 5V through formula optimization, ensuring the safety of the refrigerator in the event of a fire.
[0034] Take a mid-range household refrigerator as an example, which adopts the refrigerator bottom plate assembly of the present application. During the assembly process, the first plate surface 11, the second plate surface 12, the third plate surface 13 and the fourth plate surface 14 of the PVC part 10 are firstly integrated by the blister process. Then, the left sheet metal bracket 21 and the right sheet metal bracket 22 are respectively fixed to the two ends of the second plate surface 12 and the third plate surface 13, and connected with bolts. Finally, other components inside the refrigerator (such as a compressor, a condenser, etc.) are installed on the bottom plate assembly, and necessary debugging and testing are carried out.
[0035] By adopting the refrigerator bottom plate assembly of the present application, the production efficiency of the household refrigerator is significantly improved, and the production cost is effectively controlled. At the same time, the sealing and safety of the bottom plate are also fully guaranteed, providing users with a more reliable and safe refrigerator product.
[0036] In some embodiments of the present application, a PVC pipe groove 101 is provided on one side of the first panel 11 away from the bracket 20, and the PVC pipe groove 101 is used to place the refrigeration pipe. The provision of the PVC pipe groove 101 not only optimizes the spatial layout inside the refrigerator, but also improves the installation efficiency and overall performance of the refrigeration system.
[0037] Specifically, the PVC part 10 is the main part of the bottom plate assembly, and its four panels: the first panel 11, the second panel 12, the third panel 13 and the fourth panel 14 are integrally formed through the vacuum forming process to form a bottom plate structure that is both strong and light. Among them, the first panel 11 is located at the front end of the bottom plate assembly, away from the bracket 20. On the side of the first panel 11 away from the bracket 20, a PVC pipe groove 101 is set. This pipe groove 101 is a groove opened along the height direction of the first panel 11, which can tightly and safely accommodate the refrigeration pipe.
[0038] The refrigeration pipe is an important part of the refrigerator refrigeration system, responsible for transporting the refrigerant from the compressor to the condenser, evaporator and other components to complete the refrigeration cycle. In traditional refrigerator design, the installation of the refrigeration pipe often requires drilling or cutting on the bottom plate or other components, which not only increases the difficulty and cost of installation, but also may damage the overall structure of the bottom plate, affecting the durability and safety of the refrigerator.
[0039] The setting of the PVC pipe-threading groove 101 of the present application effectively solves this problem. The PVC pipe-threading groove 101 provides a special channel so that the refrigeration pipe can easily pass through the bottom plate without any destructive operation. This not only simplifies the installation process and improves production efficiency, but also ensures the stability and safety of the refrigeration pipe.
[0040] In addition, the design of the PVC pipe groove 101 also takes into account the spatial layout and aesthetics of the refrigerator interior. By hiding the refrigeration pipe in the PVC pipe groove 101, the refrigeration pipe can be prevented from being exposed inside the refrigerator, thereby reducing the accumulation of dust and dirt and keeping the interior of the refrigerator clean and beautiful.
[0041] It can be understood that in this embodiment, the setting of the PVC pipe groove 101 allows the refrigeration pipe to be arranged more reasonably inside the refrigerator, avoiding space waste and pipeline confusion; no drilling or cutting is required, which simplifies the installation process of the refrigeration pipe and reduces the installation cost and time. At the same time, it avoids the damage to the bottom plate structure that may be caused by drilling or cutting, and improves the durability and safety of the refrigerator.
[0042] In some embodiments of the present application, the width of the PVC pipe groove 101 is smaller than the diameter of the refrigeration pipe, and the difference between the width of the PVC pipe groove 101 and the diameter of the refrigeration pipe is 0.1-0.2 mm.
[0043] In the embodiment of the present application, the difference between the width of the PVC pipe groove 101 and the diameter of the refrigeration pipe ensures that the refrigeration pipe can be tightly embedded in the PVC pipe groove 101 during installation, avoiding the reduction of refrigeration effect or safety hazards caused by looseness. On the other hand, due to the existence of the difference, the refrigeration pipe can still maintain a certain degree of flexibility during the installation process, which is convenient for technicians to perform fine-tuning and alignment, thereby improving installation efficiency and accuracy.
[0044] In addition, the refrigerator may also encounter factors such as vibration and temperature changes during use. Since the width of the PVC pipe groove 101 is slightly smaller than the diameter of the refrigeration pipe, the refrigeration pipe will be subjected to a certain degree of squeezing after installation. This squeezing effect can be regarded as a natural fastening method, which helps to enhance the connection stability between the refrigeration pipe and the bottom plate assembly. At the same time, since the PVC material has a certain degree of elasticity and weather resistance, it can adapt to the slight deformation that may occur during the use of the refrigerator, thereby maintaining a close fit between the refrigeration pipe and the PVC pipe groove 101.
[0045] In some embodiments of the present application, transverse reinforcing ribs 102 are provided on the first plate surface 11 , and the depth of the transverse reinforcing ribs 102 is 3-5 mm.
[0046] It is understandable that by providing the transverse reinforcing ribs 102 on the first plate surface 11, the bending strength and torsional strength of the bottom plate assembly can be effectively improved, thereby enhancing its load-bearing capacity and durability. This is important for household appliances such as refrigerators that need to withstand heavy objects and vibrations for a long time. The addition of the transverse reinforcing ribs 102 makes the bottom plate assembly more stable when bearing heavy objects inside the refrigerator, reducing the risk of deformation or damage caused by uneven load bearing. It helps to maintain the balance and stability inside the refrigerator and extend the service life of the refrigerator.
[0047] Furthermore, the transverse reinforcing ribs 102 have a moderate depth and can be integrally formed with the PVC pipe grooves 101 and other structures through the blister process, so the processing difficulty and time are not significantly increased. On the contrary, due to the reinforcement effect of the transverse reinforcing ribs 102, the deformation and damage of the bottom plate assembly during subsequent processing and use can be reduced, thereby improving the overall production efficiency and economic benefits.
[0048] In some embodiments of the present application, edges of the left sheet metal bracket 21 and the right sheet metal bracket 22 away from the PVC member 10 are provided with flanges 23 , and bosses 231 and rivet holes 232 are provided on the flanges 23 .
[0049] Specifically, the flange 23 is arranged on the left sheet metal bracket 21 and the right sheet metal bracket 22, away from the edge of the PVC member 10. The flange 23 is to increase the contact area between the bracket 20 and other parts of the refrigerator (such as the box body, the door body, etc.), thereby improving the stability and firmness of the connection.
[0050] The embodiment of the present application also provides a boss 231 and a rivet hole 232 on the flange 23. The boss 231 is a protruding structure on the flange 23, which mainly plays a role of positioning and supporting. When the left sheet metal bracket 21 and the right sheet metal bracket 22 are connected to other components, the boss 231 can ensure that the positional relationship between the two is accurate, avoiding performance degradation or failure caused by installation errors.
[0051] The rivet holes 232 are used for fixing the two. By installing rivets or other fasteners in the rivet holes 232, the left sheet metal bracket 21 and the right sheet metal bracket 22 can be firmly connected to other parts of the refrigerator to form an overall stable structure. This connection method is not only simple and fast, but also has high connection strength and reliability.
[0052] It is understandable that, in this embodiment, the flange 23 increases the contact area between the bracket 20 and other components of the refrigerator, and improves the stability and firmness of the connection. The boss 231 plays a role in positioning and supporting, ensuring that the positional relationship between the various components is accurate and improving the installation efficiency. Rivets or other fasteners are installed through the rivet holes 232, so that a firm connection between the components is achieved, with high connection strength and reliability.
[0053] In some embodiments of the present application, longitudinal reinforcing ribs 103 are provided on the third plate surface 13 and the fourth plate surface 14, and the depth of the longitudinal reinforcing ribs 103 is 3-5 mm.
[0054] Specifically, the longitudinal reinforcing ribs 103 are convex structures arranged along the width direction of the third plate surface 13 and the fourth plate surface 14. Similar to the transverse reinforcing ribs 102, the depth of the longitudinal reinforcing ribs 103 is also precisely controlled between 3-5 mm. This depth design not only ensures the reinforcing effect of the reinforcing ribs, but also avoids material waste and increased processing difficulty caused by excessive depth.
[0055] In terms of positional relationship, the longitudinal reinforcing ribs 103 are closely fitted with the third plate surface 13 and the fourth plate surface 14 to form an integrated structure. This design not only enhances the bending strength and torsional strength of the bottom plate assembly, but also improves its overall rigidity and stability. At the same time, the provision of the longitudinal reinforcing ribs 103 also helps to disperse the stress on the bottom plate assembly, reducing the risk of deformation or damage caused by excessive local stress.
[0056] It is understandable that, in this embodiment, by providing the longitudinal reinforcing ribs 103 on the third plate surface 13 and the fourth plate surface 14, the bending strength and torsional strength of the bottom plate assembly can be effectively improved, thereby enhancing its overall structural strength. The provision of the longitudinal reinforcing ribs 103 helps to enhance the overall rigidity and stability of the bottom plate assembly, making it more stable and reliable when bearing heavy objects and vibrations inside the refrigerator. The addition of the reinforcing ribs enables the bottom plate assembly to distribute stress more evenly when bearing heavy objects, reduces the risk of deformation or damage caused by excessive local stress, and thus improves its load-bearing capacity.
[0057] In some embodiments of the present application, an anti-skid groove is provided on the surface of the opposite side of the left sheet metal bracket 21 and the right sheet metal bracket 22. The anti-skid groove is a continuous or discontinuous concave-convex texture. The depth of the anti-skid groove is 0.5-1.5mm and the width is 1-3mm.
[0058] The anti-skid groove is a continuous or discontinuous concave-convex texture provided on the surface of the opposite side of the left sheet metal bracket 21 and the right sheet metal bracket 22. These textures can be regular or irregular, and the specific shape and arrangement can be flexibly adjusted according to the design requirements and actual usage scenarios of the refrigerator. The depth is controlled between 0.5-1.5mm, which can not only provide sufficient friction, but also avoid the processing difficulty and cost increase caused by excessive depth. The width is controlled within the range of 1-3mm, which can increase the contact area and connection strength between components while ensuring the anti-skid effect.
[0059] In terms of positional relationship, the anti-skid groove is closely attached to the opposite side surface of the left sheet metal bracket 21 and the right sheet metal bracket 22, and is integrated with the overall structure of the sheet metal bracket. This design not only enhances the firmness and durability of the anti-skid groove, but also improves the overall aesthetics and coordination of the refrigerator.
[0060] Specifically, the concave-convex texture of the anti-skid groove can increase the friction between the sheet metal bracket and other parts of the refrigerator, thereby improving the stability and firmness of the connection between them. Even when the refrigerator is subjected to vibration or impact, it can effectively prevent the loosening or falling off of the parts. The design of the anti-skid groove can disperse the stress generated during the use of the refrigerator and reduce the risk of deformation or damage caused by excessive local stress. At the same time, the concave-convex texture can also increase the contact area between the parts, improve the strength and durability of the connection, make the refrigerator more stable and reliable during use, and reduce the safety hazards caused by loose or falling parts.
[0061] In some embodiments of the present application, shock-absorbing pads are provided at the connections between the second panel 12 and the third panel 13 of the PVC part 10 and the left sheet metal bracket 21 and the right sheet metal bracket 22. The shock-absorbing pads are made of rubber or silicone material, have a thickness of 2-5 mm, and have a shape that matches the contour of the connection between the left sheet metal bracket 21 and the right sheet metal bracket 22.
[0062] Shock-absorbing pads are arranged at the connection between the second plate surface 12 and the third plate surface 13 of the PVC member 10 and the left sheet metal bracket 21 and the right sheet metal bracket 22. The shock-absorbing pads are made of rubber or silicone materials, which have good elasticity and wear resistance, can effectively absorb and disperse vibration energy, and reduce noise generation.
[0063] The thickness of the shock-absorbing pad is controlled between 2-5 mm. This design not only ensures sufficient shock-absorbing effect, but also avoids installation difficulties and increased costs caused by excessive thickness. At the same time, the shape of the shock-absorbing pad matches the contour of the connection between the left sheet metal bracket 21 and the right sheet metal bracket 22, ensuring that the shock-absorbing pad can fit tightly at the connection to provide stable support and shock-absorbing effects.
[0064] In actual use, the shock-absorbing pad can absorb and disperse the vibration energy generated during the operation of the refrigerator, reduce the noise, and improve the user experience. The addition of the shock-absorbing pad makes the connection between the PVC part 10 and the left sheet metal bracket 21 and the right sheet metal bracket 22 more stable, and can maintain the stability of the overall structure even when the refrigerator is subjected to external impact or vibration. At the same time, the shock-absorbing pad can reduce the wear of the connection caused by vibration, thereby extending the service life of the refrigerator.
[0065] In some embodiments of the present application, a reinforcement corner is provided at the intersection of the first plate surface 11 and the second plate surface 12 of the PVC member 10, and at the intersection of the third plate surface 13 and the fourth plate surface 14. The reinforcement corner is triangular or rectangular, and the thickness of the reinforcement corner is 1.5-2 times the thickness of the PVC member 10.
[0066] The reinforcement angles are arranged at the connection intersections of the PVC member 10, i.e., the connection between the first plate surface 11 and the second plate surface 12, and the connection between the third plate surface 13 and the fourth plate surface 14. These reinforcement angles can be triangular or rectangular, and the choice of shape depends on the specific design and stress conditions of the PVC member 10. The thickness of the reinforcement angle is set to 1.5-2 times the thickness of the PVC member 10. Such a design not only ensures sufficient reinforcement effect, but also avoids material waste and increased processing difficulty caused by excessive thickness. In terms of positional relationship, the reinforcement angle fits tightly at the intersection of the PVC member 10 and is integrated with the overall structure of the PVC member 10. This design not only enhances the structural strength of the intersection, but also improves the overall rigidity and stability of the PVC member 10.
[0067] In the embodiment of the present application, the structural strength of the PVC part 10 at the intersection is significantly improved by setting the reinforcement angle, so that it can withstand greater pressure and tension, reducing the risk of deformation or damage caused by excessive force. The overall stability of the PVC part 10 is further enhanced, making the refrigerator bottom plate assembly more stable and reliable when subjected to heavy objects or vibrations. At the same time, the existence of the reinforcement angle prolongs the service life of the PVC part 10 and reduces the wear and aging caused by long-term stress.
[0068] A second aspect of an embodiment of the present application provides a refrigerator, comprising a bottom plate assembly for a refrigerator as in any one of the above embodiments.
[0069] As can be seen from the above content, the present application provides a refrigerator bottom plate assembly and a refrigerator, including: a PVC part and a bracket; the PVC part includes: a first plate surface, a second plate surface, a third plate surface and a fourth plate surface; the bracket includes: a left sheet metal bracket and a right sheet metal bracket; one side of the first plate surface is fixedly connected to the side of the second plate surface away from the third plate surface, and the first plate surface extends in a direction away from the bracket; the PVC part is an integrated molded structural part based on the blister process. After the structural optimization of the refrigerator bottom plate assembly of the present application, the sub-parts are reduced, the PVC parts are integratedly molded by blister molding, the production efficiency is high, and no assembly is required. The bracket has a flange to enhance the strength of the bracket. In addition, through the blister molding method, the PVC parts can have various pattern reinforcement ribs to improve the rigidity of the parts. The double reinforcement effect of the lines of the transverse reinforcement ribs and the longitudinal reinforcement ribs improves the rigidity of the part, and the original sheet metal beam can be eliminated, and the cost is further reduced. The refrigerator bottom plate assembly of this scheme reduces the installation process, and through the absence of splicing gaps, there is no need to increase the sealing of the sponge parts, which is efficient and reduces the cost.
