The protection structure 400 at least shields the side of the circuit board 200 away from the control panel 300.
[0035] The protection structure 400 can be made of a high-temperature-resistant and corrosion-resistant material.
[0036] Specifically, when the panel assembly is applied to a cooking appliance, the control panel 300 is located on the outer surface of the cooking appliance shell, the user can press the key 210 on the control panel 300 to control the working of the cooking appliance, and the protection structure 400 is located on the inner surface of the cooking appliance shell to protect the circuit board 200. The protection structure 400 at least shields the side of the circuit board 200 away from the control panel 300 and is made of a high-temperature-resistant and corrosion-resistant material, so that the protection structure 400 can effectively prevent water vapor, oil fume and the like from flowing to the circuit board 200. Because the protection structure 400 can withstand the erosion of water vapor, oil fume and the like for a long time, the protection structure 400 can effectively prevent the circuit board 200 from rusting or the control circuit from corroding for a long time, thereby ensuring that the panel assembly can work normally for a long time and the service life of the cooking appliance is guaranteed.
[0037] In some embodiments, with reference to Figure 1 and Figure 2The protection structure 400 is a protection inner plate 410 with a certain hardness, which is arranged on the side of the circuit board 200 away from the control panel 300. The protection inner plate 410 can be directly fixedly connected to the inner side of the circuit board 200, or the protection inner plate 410 can be integrally connected or assembled with the shell support 100 to be fixed on the inner side of the circuit board 200. It can be understood that the protection structure 400 adopts the protection inner plate 410 with a certain hardness, which can effectively shield the inner side of the circuit board 200 when applied, thereby preventing water vapor, cooking fumes and the like from flowing to the circuit board 200, and thus effectively protecting the circuit board 200. At the same time, the protection inner plate 410 can also effectively prevent the collision of the circuit board 200, thereby ensuring the safe application of the circuit board 200.
[0038] Further, with reference to Figure 2 and Figure 3 The edge of the protection inner plate 410 is provided with a surrounding edge 411, and the shape of the surrounding edge 411 is arranged according to the shape of the circuit board 200, so as to surround the four sides of the circuit board 200. It can be understood that the protection inner plate 410 is further wrapped around the circuit board 200 by the surrounding edge 411, thereby further preventing water vapor, cooking fumes and the like from flowing to the circuit board 200, and thus avoiding the problems of rusting of the circuit board 200 or corrosion of the control circuit.
[0039] In some embodiments, with reference to Figure 3 The protection inner plate 410 is formed by vacuum forming of PET or PPT material. It can be understood that the protection inner plate 410 is made of PET or PPT material, which has good high-temperature resistance or corrosion resistance. Therefore, the protection inner plate 410 arranged on the inner side of the circuit board 200 can effectively prevent water vapor, cooking fumes and the like from flowing to the circuit board 200 for a long time, thereby ensuring the safe application of the circuit board 200 and thus ensuring the service life of the cooking appliance. In addition, the protection inner plate 410 is formed by vacuum forming, and the anti-skid inner plate is simple to manufacture and has low cost, thereby effectively saving the manufacturing cost of the panel assembly.
[0040] In some embodiments, with reference to Figure 2 The panel assembly further comprises a loading rack 500 arranged between the control panel 300 and the circuit board 200. One side of the loading rack 500 is assembled to the inner side of the control panel 300, or the loading rack 500 is assembled to the shell support 100 to be located on the inner side of the control panel 300, and the other side of the loading rack 500 is assembled to the circuit board 200. At the same time, the loading rack 500 is provided with a plurality of key 210 holes, and the number of the key 210 holes is the same as that of the keys 210. The keys 210 are arranged one by one in the key 210 holes to extend to the position of the control panel 300.
[0041] It can be understood that, through the arrangement of the loading rack 500, the circuit board 200 can be pre-assembled to the inner side of the loading rack 500, and the loading rack 500 is assembled to the inner side of the control panel 300, so that the circuit board 200 can be conveniently and accurately assembled to the inner side of the control panel 300, and the keys 210 of the circuit board 200 are arranged corresponding to the control panel 300. At the same time, the key 210 hole of the loading rack 500 also has a guiding effect on the key 210, so that when the key 210 is subjected to external action, the key 210 can stably move in and out, thereby reducing the deflection force in other directions, and further ensuring the service life of the key 210.
[0042] Furthermore, the circuit board 200 is assembled to the loading rack 500, and then the loading rack 500 is assembled to the inner side of the control panel 300, so that the loading rack 500 makes the circuit board 200 more stably assembled to the inner side of the control panel 300. When the circuit board 200 is subjected to the force of the key 210, the loading rack 500 has a good supporting effect on the circuit board 200, thereby ensuring the safe application of the circuit board 200.
[0043] In some embodiments, with reference to Figure 2 With Figure 3 The protective inner plate 410 is provided with a plurality of first connecting holes 412 around it, and the circuit board 200 is provided with a plurality of second connecting holes 220 around it. The first connecting holes 412 and the second connecting holes 220 are arranged in equal numbers and are aligned one by one; at the same time, the panel assembly further comprises fastening screws 600, which are arranged in equal numbers with the first connecting holes 412 and the second connecting holes 220. Each fastening screw 600 is arranged in the first connecting hole 412 and the second connecting hole 220 and is connected with the loading rack 500. Thus, the fastening screw 600 simultaneously fixes the loading rack 500, the protective inner plate 410 and the circuit board 200 together.
[0044] It can be understood that the loading rack 500, the protective inner plate 410 and the circuit board 200 are tightly assembled together by the fastening screw 600. In this way, the loading rack 500, the protective inner plate 410 and the circuit board 200 can be compactly assembled together, so as to be adapted to the compact space of the cooking container. Therefore, the panel assembly has good adaptability. Furthermore, the loading rack 500, the protective inner plate 410 and the circuit board 200 adopt the above-mentioned connecting structure, which is simple in structure, convenient to install, low in manufacturing cost, and can prevent the circuit board 200 from rusting or the control circuit from corroding for a long time.
[0045] Instead of the above-mentioned arrangement of the protective inner plate 410, in some embodiments, with reference to Figure 2The protective structure 400 is a flexible film (not shown in the figure) which is at least attached to the side of the circuit board 200 away from the control panel 300. The flexible film is made of PVC material. It can be understood that the flexible film is attached to the side of the circuit board 200 away from the control panel 300, so that the water vapor, oil fume and the like can be effectively prevented from flowing to the circuit board 200.

[0046] Further, the flexible film and the loading rack 500 have an area larger than the area of the circuit board 200, so that the edge of the flexible film can be attached to the edge area of the loading rack 500. Thus, the flexible film cooperates with the loading rack 500 to seal the circuit board 200 between the loading rack 500 and the flexible film, thereby further preventing the water vapor, oil fume and the like from flowing to the circuit board 200, and ensuring the safe use of the circuit board 200.
