Description

Technical Field

[0001] The utility model relates to the technical field of ovens, and specifically relates to a formed metal plate for the outer layer of an oven. Background Technique

[0002] An oven, also called a roasting oven, a drying oven, etc., is a sealed electrical appliance used for roasting food or drying products, which is divided into household appliances and industrial ovens. A household oven can be used to process some pasta. An industrial oven is a device used for drying products in industry, which can be powered by electricity or gas. Due to the heating reason, the outer layer of the oven generally adopts a metal plate with certain strength and heat resistance.

[0003] At present, most of the formed metal plates for the outer layer of ovens on the market adopt a single-layer metal material. Although it has certain strength and heat resistance, there are many deficiencies in the heat insulation effect and weight control. The single-layer metal plate has fast heat transfer, resulting in a relatively high temperature on the outer surface of the oven, which is prone to cause the risk of scalding. Moreover, the single-layer metal plate must rely on thickness and material density to provide strength and rigidity, which is not conducive to the convenient use of the oven. Summary of the Invention

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, an outer layer formed metal plate of an oven includes an inner high-temperature-resistant metal thin plate 1, a middle layer, and an outer nano-coating 5.

[0019] In the specific implementation process, as shown in Figure 1 , Figure 2 and Figure 3 , one side of the inner high-temperature-resistant metal thin plate 1 is connected to the middle layer. The material of the inner high-temperature-resistant metal thin plate 1 is stainless steel. The middle layer includes an inner aluminum plate 2, an aluminum honeycomb core 4, and an outer aluminum plate 3. One side of the inner high-temperature-resistant metal thin plate 1 is fixedly connected to the inner aluminum plate 2. One side of the inner aluminum plate 2 is fixedly connected to the aluminum honeycomb core 4. One side of the aluminum honeycomb core 4 is fixedly connected to the outer aluminum plate 3. The outer nano-coating 5 is coated on one side of the outer aluminum plate 3.

[0020] It should be noted that: The outer formed metal plate of this oven adopts a multi-functional structure. The inner layer uses an inner high-temperature resistant metal thin plate 1 made of stainless steel, which has excellent high-temperature resistance, corrosion resistance, and mechanical strength characteristics, and can work stably for a long time in a high-temperature environment, ensuring basic strength and heat resistance. The middle layer is composed of an inner aluminum plate 2, an aluminum honeycomb core 4, and an outer aluminum plate 3. The middle layer is an aluminum honeycomb structure formed by the inner aluminum plate 2, the aluminum honeycomb core 4, and the outer aluminum plate 3. The aluminum honeycomb core 4 in the honeycomb structure provides multiple dispersed heat conduction paths. Compared with a single-layer metal plate, these paths are more tortuous, and it takes longer time and path for heat to conduct through, thus reducing the heat conduction efficiency. Moreover, the aluminum honeycomb core 4 of the honeycomb structure is filled with air, and air is an excellent heat insulator. The honeycomb structure forms a natural heat insulation barrier by increasing the air layer, reducing heat conduction. And a single-layer metal plate is a continuous heat bridge, and heat can be quickly conducted from one side to the other side. However, due to the discontinuous honeycomb core in the middle of the aluminum honeycomb core 4, the heat bridge effect is greatly weakened, further reducing heat conduction. At the same time, the multi-layer structure increases the heat conduction path, further reducing the heat conduction rate. And using the lightweight aluminum honeycomb core 4 to replace the traditional heavy metal plate, the hexagonal lattice structure of the aluminum honeycomb core 4 can disperse stress and load, making it not easy to buckle or deform, and at the same time using less material, achieving the balance of lightweight and high strength. And the outer nano-coating 5 has anti-fouling, scratch-resistant, and high-temperature resistant properties. In summary, the outer formed metal plate of this oven adopts a multi-layer structure. The inner high-temperature resistant metal thin plate 1 ensures basic strength and heat resistance. The honeycomb structure design of the middle layer not only effectively reduces heat conduction but also significantly reduces the weight of the plate, thus significantly improving the heat insulation effect and reducing the weight, making the oven safer and more convenient in daily use.

[0021] The inner aluminum plate 2 is fixedly adhered to the inner high-temperature resistant metal thin plate 1 through a ceramic-based adhesive. The aluminum honeycomb core 4 is fixedly adhered to the inner aluminum plate 2 and the outer aluminum plate 3 through a ceramic-based adhesive. The ceramic-based adhesive can maintain good bonding performance at high temperatures, making the structure of the plate more stable.

[0022] Reference Figure 1 、 Figure 2 and Figure 3 As shown in, a matching aluminum frame 6 is provided between the inner aluminum plate 2 and the outer aluminum plate 3. The aluminum frame 6 is sleeved on the aluminum honeycomb core 4. One end of the aluminum frame 6 is fixedly connected to one side of the inner aluminum plate 2, and the other end of the aluminum frame 6 is fixedly connected to one side surface of the outer aluminum plate 3. By setting the aluminum frame 6, it not only plays a protective role for the aluminum honeycomb core 4 but also makes the structure of the plate more stable.

[0023] The aluminum frame 6 is fixedly adhered to the inner aluminum plate 2 and the outer aluminum plate 3 through a ceramic-based adhesive. The ceramic-based adhesive can maintain good bonding performance at high temperatures, making the structure of the aluminum frame 6 more stable.
