[0114] As shown in Figure 6 , the warm cutting board further comprises a reflecting component 820, which is arranged between the heat insulation component 500 and the heating coating 400 and can reflect the heat generated by the heating coating 400 to the second panel 300.

Moreover, by arranging the reflecting cover between the heat insulation component 500 and the heating coating 400, the heat transferred from the heating coating 400 to the heat insulation component 500 is reduced, the heat insulation effect of the heat insulation component 500 is improved, the heat insulation pressure of the heat insulation component 500 is reduced, and thus the thickness of the heat insulation component 500 can be reduced, the space occupied by the heat insulation component 500 in the mounting cavity 110 is reduced, and the utilization rate of the space in the mounting cavity 110 is improved.

[0116] The warm cutting board provided by the embodiment further comprises the following technical features in addition to the technical features of the above embodiments.

[0117] As shown in Figure 6 , the warm cutting board further comprises an insulating layer 830, which is arranged between the heating coating 400 and the second panel 300 or arranged on the side of the second panel 300 away from the heating coating 400.

[0118] In this embodiment, the warming plate further comprises an insulating layer 830 arranged between the heating coating 400 and the second panel 300 or arranged on the side of the second panel 300 away from the heating coating 400. The insulating layer 830 can improve the insulation effect of the second panel 300. When the warming plate is working, the second panel 300 is heated. By arranging the insulating layer 830 on the second panel 300, the high temperature can be prevented from affecting the insulation effect of the second panel 300, the durability of the second panel 300 is improved, and the production cost of the second panel 300 is reduced.

[0119] The warming plate provided in this embodiment further comprises the following technical features in addition to the technical features of the above embodiments.

[0120] The heating coating 400 comprises at least one of a graphene coating and a metal oxide coating.

[0121] In this embodiment, the heating coating 400 comprises at least one of a graphene coating and a metal oxide coating. The heating coating 400 can be attached to the second panel 300 by a printing or evaporation process, which reduces the installation difficulty, does not need to additionally arrange a heating device, and reduces the cost. Since the graphene coating and the metal oxide coating can be attached to the second panel 300 by the printing or evaporation process, the axial height of the second panel 300 can be reduced, and the axial height of the warming plate can be reduced, thereby realizing the light and thin design and the light weight design of the warming plate, facilitating the use of the customer, and improving the stability of the warming plate.

[0122] The warming plate provided in this embodiment further comprises the following technical features in addition to the technical features of the above embodiments.

[0123] The first panel 200 is a tempered glass panel.

[0124] The second panel 300 is a high borosilicate glass panel or a microcrystalline panel.

[0125] In this embodiment, the first panel 200 is a tempered glass panel, which reduces the cost of the first panel 200. The second panel 300 is a high borosilicate glass panel or a microcrystalline panel, which improves the heat resistance of the second panel 300.

[0126] Further, the first panel 200 can be heated to a first temperature value, and the second panel 300 can be heated to a second temperature value, the second temperature value being greater than the first temperature value. By setting different heating limits for the first panel 200 and the second panel 300, the functionality of the warming plate can be improved, and customers can select different panels for heating according to actual conditions, thereby enriching the heat preservation effect of the warming plate. At the same time, by bonding the heating coating 400 to the second panel 300, the second panel 300 can be heated through the heating coating 400, which can not only increase the heating temperature of the first panel 200, but also simplify the heating structure, reduce the structural complexity of the warming plate, improve the assembly efficiency, and reduce the production cost of the warming plate. By setting the heating coating 400 to heat the second panel 300, the weight and axial height of the warming plate can be reduced, thereby realizing the design of light and thin and light weight of the warming plate, and facilitating the use of customers. By setting the second temperature value to be greater than the first temperature value, the heat emitted by the second panel 300 can be used to reheat cold food in the tableware, thereby enriching the functionality of the warming plate and meeting the different heating needs of customers.

[0127] Further, the heating coating 400 can be coated on the second panel 300 by printing or evaporation process, thereby simplifying the operation steps and reducing the operation difficulty.

[0128] Further, since the heating coating 400 occupies a small space, the axial height of the warming plate can be reduced. After the tableware is placed on the warming plate, the stability of the tableware can be improved by reducing the axial height, thereby improving the structural stability of the warming plate and facilitating daily use.

[0129] Further, by setting different heating limits for the first panel 200 and the second panel 300, and the second temperature value being greater than the first temperature value, the second panel 300 can be heated to a medium temperature to heat and preserve the tableware, thereby improving the heating efficiency of the warming plate and enriching the heat preservation function of the warming plate.

[0130] Specifically, when using the warming plate, since the limit temperature of the second panel 300 is greater than that of the first panel 200, customers can use the first panel 200 to preserve food, or use the second panel 300 to reheat cold food, thereby improving the heating efficiency.

[0131] Further, the second panel 300 can be heated to a second temperature value, and the second temperature value is greater than or equal to 140 degrees Celsius, thereby the heat emitted by the second panel 300 can be used to reheat cold food in the tableware, thereby enriching the functionality of the warming plate and meeting the different heating needs of customers. At the same time, the second temperature value is less than or equal to 600 degrees Celsius, which can not only ensure the heating efficiency, but also reduce the energy consumption, the high temperature resistance requirement of the second panel 300, and the cost.

[0132] Further, the warm plate further comprises a third panel, the third panel can be heated to a third temperature value, the second temperature value is less than the third temperature value, and the food can be cooked and heated by the third panel. By simultaneously arranging the first panel 200, the second panel 300 and the third panel with different temperature values, the different heating and keeping warm needs of the user can be met.

[0133] The third panel is a microcrystalline panel. Since the third temperature value generated at the third panel is greater than the first temperature value and the second temperature value, the third panel is a high-temperature area. Therefore, the third panel is arranged as a microcrystalline panel to play a role of high-temperature resistance and improve the durability of the third panel.

[0134] Since the first panel 200 is at the first temperature value, which is less than the third temperature value and the second temperature value, the first panel 200 is a low-temperature area. Therefore, the first panel 200 is arranged as a tempered glass panel to ensure the durability while reducing the cost. Since the second panel 300 is a medium-temperature area, the high-boron-silicon glass panel or the microcrystalline panel can also improve the high-temperature resistance of the second panel 300 and improve the durability.

[0135] Further, the number of the second panels 300 is multiple, the maximum temperature value generated at the second panel 300 is the second temperature value, and the second temperature value is greater than the first temperature value and less than the third temperature value. Therefore, the second panel 300 can provide medium-temperature heating for the warm plate. By arranging multiple second panels 300 along the circumference of the first panel 200, the heating efficiency of the warm plate can be improved, the energy consumption can be reduced, and the use needs of the user can be met.

[0136] Further, the warm plate further comprises a heating disc, which is arranged in the mounting cavity 110 and opposite to the third panel, and can heat the third panel to the third temperature value. The third panel can be heated to facilitate the warm plate to keep warm the food material.

[0137] Since the third temperature value is greater than the second temperature value and the first temperature value, the third panel is a high-temperature area, and the heating body of the high-temperature heating area is the heating disc. The heating disc can be an electric ceramic stove disc or an electromagnetic stove disc.

[0138] The embodiment provides a warm plate, in addition to the technical features of the above-mentioned embodiments, the embodiment further comprises the following technical features.

[0139] As shown in Figure 3 The warm plate further comprises a heating wire film 840, which is arranged on the side of the first panel 200 close to the mounting cavity 110.

[0140] In the embodiment, the hot plate further comprises a heating wire film 840 arranged on the side of the first panel 200 close to the installation cavity 110, so as to heat and keep warm the food placed on the first panel 200 by the heating wire film.
