[0020] In order to more clearly understand the above-mentioned purposes, technical solutions and advantages of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application, and detailed understanding of how to solve the problems raised in the above-mentioned background art.

[0021] As shown in Figure 1 and Figure 2 A shockproof high-strength bottom plate 1 structure, comprising a bottom plate 1 and a flange 2 integrally formed with the bottom plate 1, the flange 2 is arranged along the thickness direction of the bottom plate 1, and the flange 2 is connected with the four peripheral edges of the bottom plate 1, the bottom plate 1 is sequentially provided with a first convex 11, a second convex 13 and a third convex 15 from inside to outside, so that the second convex 13 forms a first support surface 12 and a second support surface 14 between the first convex 11 and the third convex 15 respectively.

[0022] Through the above-mentioned scheme, the first convex 11, the second convex 13, the third convex 15 and the flange 2 are arranged on the bottom plate 1, which significantly improves the strength of the bottom plate 1, so that the bottom plate 1 is not easy to deform during use, and the internal parts of the electrical appliance can be placed on the first support surface 12 and the second support surface 14, when the parts are installed and pressure is applied to the bottom plate 1, the concave of the bottom plate 1 can be avoided, and the balance of the bottom plate 1 can be ensured, and the shaking or deviation caused by the vibration of the electrical appliance during operation can be avoided.

[0023] In this embodiment, the bottom plate 1 and the flange 2 are integrally formed by stamping or hydraulic forming. The thickness of the bottom plate 1 is 1.2 mm. The bottom plate 1 can be made of a galvanized sheet to improve corrosion resistance, decorative properties, wear resistance, etc. The flange 2 is formed by bending the outer ring part of the bottom plate 1. The extension direction of the flange 2 is the direction of the bottom plate 1 towards the inside of the shell. The direction of the bottom plate 1 from the inside to the outside is the direction of the center towards the periphery edge. The side of the bottom plate 1 for mounting parts is the inner wall surface, and the other side is the outer wall surface. The first support surface 12 and the second support surface 14 are formed by pressing from the outer wall surface to the inner wall surface direction, so that the outer wall surface of the bottom plate 1 forms a concave structure corresponding to the first support surface 12 and the second support surface 14, and the outer wall surface of the bottom plate 1 forms a convex structure corresponding to the first convex 11, the second convex 13 and the third convex 15. The first convex 11 is cross-shaped, and the third convex 15 is connected with the periphery edge of the bottom plate 1. At the same time, the bottom plate 1 is provided with a plurality of through holes, which can ventilate and intake air, and quickly discharge water when internal water accumulation occurs.

[0024] As shown in Figure 1 , as an improved specific embodiment, the second convex 13 and the third convex 15 are both in a meandering structure. Specifically, the second convex 13 is inside the third convex 15, and the first convex 11 is inside the second convex 13, forming a structure of multiple circles of reinforcing ribs, improving the strength of the bottom plate 1, and allowing internal parts to be fixed between the first support surface 12 and the second support surface 14. The first support surface 12 and the second support surface 14 are coplanar, ensuring the placement area and stability of the parts.

[0025] As shown in Figure 1 and Figure 2 , as an improved specific embodiment, the four corners of the bottom plate 1 are provided with mounting holes 16, and the mounting holes 16 are mounted with feet 3. Specifically, the mounting holes 16 are four, corresponding to the four feet 3. Each foot 3 can be independently adjusted, so that the feet 3 can play a supporting and balancing role. The feet 3 are made of nylon, which has impact resistance, wear resistance, anti-aging, easy processability, environmental protection and sustainability. When subjected to external impact, based on its viscoelastic properties, it effectively reduces vibration by absorbing and dispersing impact force, playing a shock-absorbing role.

[0026] As shown in Figure 1 and Figure 2 , as an improved specific embodiment, the edge of the mounting hole 16 is an external thread structure with a gap between the leading end and the trailing end, and the foot 3 is provided with an internal thread structure. The external thread structure and the internal thread structure are matched to screw the foot 3 and the bottom plate 1. Specifically, the foot 3 can be a screw, which can be quickly disassembled. At the same time, the screw is installed from the outer wall surface to the inner wall surface direction. The gap facilitates the installation of the screw. By tightening or loosening each foot 3, the height between the bottom plate 1 and the bottom surface can be adjusted.

[0027] As Figure 1 shown, as an improved specific embodiment, the flange 2 is provided with a plurality of screw holes 21. Specifically, the screw holes 21 are internally threaded holes, when the flange 2 and the annular frame of the shell are connected, the screw can be screwed into the internally threaded holes through the annular frame, which helps the shell to be quickly disassembled and assembled.

[0028] It is worth noting that: the bottom plate 1 in the embodiment is used in a dryer to carry a heating system, a ventilation system and the like, but can also be used in kitchen appliances such as a microwave oven and an electric oven, and refrigeration appliances such as a household refrigerator and a cold drink machine.

[0029] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solutions falling within the scope of the present application are within the protection scope of the present application. It should be pointed out that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application, these improvements and decorations should also be considered as the protection scope of the present application.
