Abstract
Description
Technical Field
[0001] This invention relates to the technical field of air conditioning devices, and more specifically, to an air conditioner. Background Technology
[0002] Air conditioners, as a common temperature-regulating appliance, have long been a staple in households. As people's functional needs for air conditioners become increasingly diverse, they are also giving more consideration to their price.
[0003] The price of an air conditioner is closely related to its cost. In existing technology, the cost of components such as the rear panel of an air conditioner is relatively high. However, the distribution of materials is problematic. In some areas, there is an excess of material, resulting in waste, while in other areas that require reinforcement and fit, the strength is poor due to a lack of material. Therefore, a solution is needed to address these issues. Summary of the Invention
[0004] The purpose of this invention is to provide an air conditioner that solves the technical problem of high cost of components such as the rear panel of the air conditioner in the prior art.
[0005] The air conditioner provided by the present invention includes an injection-molded plate, the injection-molded plate including a plate body and an assembly structure, the plate body including a main body thinning area and a mating reinforcement area, the assembly structure being disposed in the mating reinforcement area, and the assembly structure being used to install the accessories to be assembled onto the injection-molded plate.
[0006] The air conditioner provided by this invention can produce the following beneficial effects:
[0007] The air conditioner provided by this invention divides the injection-molded sheet into a main thinning area and a mating reinforcement area. Specifically, the main body of the sheet has a thinned structure, while the mating portion with the assembly structure is a reinforced structure. The main thinning area uses less material due to the reduced wall thickness, thus lowering production costs; the mating reinforcement area ensures assembly strength through structural reinforcement. Therefore, if the rear panel and other components of the air conditioner adopt the structure of the injection-molded sheet provided by this invention, not only can assembly strength be guaranteed, but production costs can also be significantly reduced.
[0008] Furthermore, the length of the injection-molded plate is greater than or equal to 1.5m, and the thickness of the main body thinning zone ranges from 2.5mm to 2.8mm.
[0009] This technical solution significantly reduces the material usage of large injection-molded panels such as rear panels, thereby substantially lowering costs. Furthermore, after various tests, rear panels with a length of 1.5m or more, when their thickness is within the range of 2.5mm to 2.8mm, pass all tests, ensuring compliance with usage requirements. In other words, for injection-molded panels such as rear panels with a length of 1.5m or more, this thickness range satisfies both usage requirements and achieves substantial cost reduction.
[0010] Furthermore, the thickness of the reinforcing region is greater than the thickness of the main body thinning region.
[0011] This technical solution increases structural strength by thickening the reinforced area, making it simple and reliable.
[0012] Furthermore, a transition zone is provided between the mating reinforcement zone and the main body thinning zone, and the thickness of the transition zone gradually decreases from the mating reinforcement zone to the main body thinning zone.
[0013] Under this technical solution, the transition zone serves as a connection and transition between the reinforcement zone and the main thinning zone, effectively avoiding stress concentration caused by the sudden change in thickness when the reinforcement zone of the plate directly changes to the main thinning zone, thereby improving the overall strength of the plate.
[0014] Furthermore, there is a thickness difference between the reinforcing region and the main thinning region, and the width of the transition region is positively correlated with the thickness difference.
[0015] Under this technical solution, the transition between the reinforcement zone and the main thinning zone is smoother, and the stress concentration caused by the change in thickness is also weaker.
[0016] Furthermore, the width of the transition zone is 40 to 60 times the thickness difference.
[0017] Under this technical solution, if the thickness of the main thinning area is 2.7mm and the thickness of the reinforcing area is 3.2mm, then the thickness of the transition area ranges from 20mm to 30mm. With this setting, the width of the transition area is moderate, and from an aesthetic perspective, the transition is smoother and more natural.
[0018] Furthermore, the transition area and the transition area are rounded, and / or the transition area and the main body thinning area are rounded.
[0019] Under this technical solution, the transition between the reinforcement zone and the transition zone is smooth and gradual, and the transition zone and the main thinning zone are also smooth and gradual. That is, the thickness change of the entire plate is relatively smooth and gradual, which can further reduce the stress concentration phenomenon on the entire plate when it is under stress, and the structural strength of the entire plate is further increased.
[0020] Furthermore, the distance between the assembly structure and the edge of the mating reinforcement area ranges from 15mm to 30mm.
[0021] Under this technical solution, the distance between the assembly structure and the edge of the mating reinforcement area is appropriate, which can both enable the mating reinforcement area to resist the force during disassembly and assembly, and maximize the range of the main body thinning area to reduce costs.
[0022] Furthermore, the injection-molded panel is the rear panel of an air conditioner. Attached Figure Description

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0037] This embodiment provides an air conditioner, such as... Figure 7 and Figure 8 As shown, the air conditioner includes an injection-molded panel, which includes a panel body 110 and an assembly structure 120. The panel body 110 includes a main body thinning area 111 and a mating reinforcement area 113. The assembly structure 120 is disposed in the mating reinforcement area 113 and is used to install the accessories to be assembled onto the injection-molded panel.
[0038] The air conditioner provided in this embodiment divides the injection-molded sheet 110 into a main thinning area 111 and a mating reinforcement area 113. That is, the main body of the sheet 110 is a thinned structure, while the mating part with the assembly structure 120 is a reinforced structure. The main thinning area 111 uses less material due to the reduced wall thickness, thereby lowering production costs; the mating reinforcement area 113 ensures assembly strength through structural reinforcement. Therefore, if the rear panel 100 and other panels of the air conditioner adopt the structure of the injection-molded sheet provided in this embodiment, not only can assembly strength be guaranteed, but production costs can also be significantly reduced.
[0039] Specifically, in this embodiment, the "assembly structure" includes positioning components, limiting components, and fixing components. The positioning components include positioning posts, the limiting components include turrets, and the fixing components include clips and studs. Of course, the "assembly structure" is not limited to these. As long as it can play a role in positioning, limiting, or fixing during the assembly and disassembly process, its setting part can be set as the mating reinforcement area 113.
[0040] More specifically, in this embodiment, as Figures 1 to 6 As shown, where, Figure 1 This is a schematic diagram of the injection-molded panel of the air conditioner provided in this embodiment from a first-view perspective. Figure 2 and Figure 3 They are respectively Figure 1 Enlarged structural diagrams at points A and B in the middle; Figure 4 This is a schematic diagram of the assembly structure of the injection-molded plate, evaporator, and reinforcing strip of the air conditioner provided in this embodiment. Figure 5 and Figure 6 They are respectively Figure 4 Enlarged structural diagrams at points C and D. (See attached diagram.) Figure 2 As shown and referenced Figure 1 , Figure 4 and Figure 5 The rear panel 100 has a positioning element 121 and a first limiting element 122 on its body 110. The positioning element 121 is used to position the lower support 210 of the evaporator 200, and the first limiting element 122 is used to limit the lower support 210. Figure 3 As shown and referenced Figure 1 , Figure 4 and Figure 6 The rear panel 100 is also provided with a second limiting member 123 and a fixing member 124 on the panel 110. The second limiting member 123 is used to limit the reinforcing strip 300, and the fixing member 124 is used to fix the reinforcing strip 300.
[0041] Specifically, in this embodiment, the length of the injection-molded plate is greater than or equal to 1.5m, and the thickness of the main body thinning region 111 ranges from 2.5mm to 2.8mm, for example: Figure 8 The thickness 'a' of the main thinning area 111 of the rear panel 100 is 2.7 mm. This configuration significantly reduces the material used in large injection-molded panels such as the rear panel 100, thereby substantially lowering costs. Furthermore, after various tests, rear panels 100 with a length of 1.5 m or more, when their thickness is within the range of 2.5 mm to 2.8 mm, pass all tests, ensuring compliance with usage requirements. In other words, for injection-molded panels such as the rear panel 100 with a length of 1.5 m or more, this thickness range satisfies usage requirements while significantly reducing costs.
[0042] Specifically, in this embodiment, as Figure 8 As shown, the thickness of the reinforcing zone 113 is greater than the thickness of the main thinning zone 111. With this configuration, the reinforcing zone 113 increases structural strength through thickening, which is simple and reliable.
[0043] It should be noted that in other embodiments of this application, the reinforcement area 113 is not limited to ensuring the structural strength of the mating part of the plate 110 by increasing the wall thickness. The structural strength can also be increased by other means, such as setting reinforcement ribs or other reinforcement structures. Of course, it is also possible to both thicken the wall and set reinforcement structures.
[0044] Specifically, in this embodiment, as Figure 8As shown, a transition zone 112 is provided between the reinforcing zone 113 and the main thinning zone 111, and the thickness of the transition zone 112 gradually decreases from the reinforcing zone 113 to the main thinning zone 111. In this configuration, the transition zone 112 serves to connect the reinforcing zone 113 and the main thinning zone 111, effectively preventing stress concentration caused by the sudden change in thickness when the plate 110 changes directly from the reinforcing zone 113 to the main thinning zone 111, thereby improving the overall strength of the plate 110.
[0045] Specifically, in this embodiment, there is a thickness difference between the reinforcing region 113 and the main body thinning region 111, and the width of the transition region 112 is positively correlated with the aforementioned thickness difference. With this configuration, the transition between the reinforcing region 113 and the main body thinning region 111 is smoother, and the stress concentration caused by the thickness change is also weaker.
[0046] More specifically, in this embodiment, the width of the transition region 112 is 40 to 60 times the thickness difference between the reinforcing region 113 and the main body thinning region 111. For example, if the thickness a of the main body thinning region 111 is 2.7 mm and the thickness b of the reinforcing region 113 is 3.2 mm, then the thickness of the transition region 112 ranges from 20 mm to 30 mm. With this setting, the width of the transition region 112 is moderate, and from an aesthetic perspective, the transition is smoother and more natural.
[0047] Specifically, in this embodiment, the transition between the reinforcing region 113 and the transition region 112 is rounded, as is the transition between the transition region 112 and the main body thinning region 111. This arrangement ensures a smooth and gradual transition between the reinforcing region 113 and the transition region 112, and also between the transition region 112 and the main body thinning region 111. In other words, the thickness variation of the entire plate 110 is relatively smooth and gradual, which further reduces stress concentration on the plate 110 when under stress, and further increases the structural strength of the entire plate 110.
[0048] It should be noted that in other embodiments of this application, the transition between the reinforcing region 113 and the transition region 112, and the transition region 112 and the main body thinning region 111, may also have only one rounded corner transition.
[0049] Specifically, in this embodiment, the distance between the assembly structure 120 and the edge of the mating reinforcement area 113 ranges from 15mm to 30mm. This arrangement provides a suitable distance between the assembly structure 120 and the edge of the mating reinforcement area 113, ensuring that the mating reinforcement area 113 has sufficient strength to resist forces during assembly and disassembly, while also maximizing the area of the main body thinning area 111 to reduce costs.
[0050] Specifically, in this embodiment, the injection-molded panel is the rear panel 100 of the air conditioner.
[0051] However, it should be noted that the injection-molded panel of the air conditioner provided in this application is not limited to the rear panel 100. For example, in other embodiments of this application, the injection-molded panel can also be the front panel of the air conditioner, or other injection-molded panels with a longer length on other products. That is, injection-molded panels with a longer length can all adopt the technical solution of this application, which can not only ensure assembly strength, but also significantly reduce production costs.
[0052] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
