[0114] In this embodiment, the reflector 600 is provided with a limiting notch 630, and the limiting rib 510 provided on the support member 500 is located within the limiting notch 630. The limiting rib 510 cooperates with the limiting notch 630 to realize the installation and positioning of the support member 500, thereby improving the stability of the support member 500 during the use of the food warmer. Furthermore, the cooperation between the limiting rib 510 and the limiting notch 630 can prevent the support member 500 from shifting during the use of the food warmer, thereby reducing the probability of the temperature detection member 810 contacting the protective cover and further improving the safety of the food warmer during use.

[0115] Specifically, there can be multiple limiting ribs 510, which are arranged in parallel and contact the edge of the limiting notch 630 respectively.

[0116] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0117] like Figure 1 As shown, the limiting notch 630 is arranged at the edge of the first mounting port 610 and is recessed into the side wall of the reflector 600.

[0118] In this embodiment, the limiting notch 630 is arranged at the edge of the first mounting port 610 and recessed into the side wall of the reflector 600, so that the limiting notch 630 can be formed in one step with the first mounting port 610, which simplifies the processing technology of the reflector 600, reduces the processing difficulty of the reflector 600, and improves the processing efficiency of the reflector 600.

[0119] Furthermore, the first mounting port 610 can be a round port, a square port, or a polygonal port.

[0120] The number of limit gaps 630 can be one or more.

[0121] When there are multiple limiting notches 630, the multiple limiting notches 630 are arranged circumferentially along the first mounting port 610.

[0122] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0123] like Figure 2 and Figure 2 As shown, the limiting notch 630 is provided on the bottom wall of the reflector 600; the support member 500 is provided on the bottom wall of the reflector 600 near the heating coating 400, and the limiting rib 510 protrudes from the support member 500 in a direction away from the heating coating 400.

[0124] In this embodiment, the limiting notch 630 is provided on the bottom wall of the reflector 600, and the support member 500 is provided on the side of the bottom wall of the reflector 600 near the heating coating 400. The limiting rib 510 protrudes from the support member 500 in a direction away from the heating coating 400. When assembling the support member 500, the support member 500 can be assembled on the bottom wall of the reflector 600, and the limiting rib 510 and the limiting notch 630 can be installed opposite each other, thereby realizing the assembly of the support member 500 and reducing the assembly difficulty of the warming plate.

[0125] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0126] like Figure 2 As shown, the reflector 600 is provided with a through hole 640; the support component 500 is provided with a mounting post 520, which is opposite to the through hole 640; the warming plate also includes a connector 830, which passes through the through hole 640 and is connected to the mounting post 520.

[0127] In this embodiment, the mounting post 520 is opposite to the through hole 640, and the connector 830 passes through the through hole 640 and is connected to the mounting post 520 to fix the support component 500 and improve the stability of the support component 500 during the operation of the warming board.

[0128] Specifically, the connector 830 may be a screw, bolt, or rivet.

[0129] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0130] The support component 500 is bonded to the reflector 600; or the support component 500 is snapped into the reflector 600.

[0131] In this embodiment, the support component 500 is bonded to the reflector 600 to fix the support component 500, and the assembly process of the support component 500 is further simplified by fixing the support component 500 by bonding.

[0132] The support component 500 is snapped onto the reflector 600 to fix the support component 500. The snap-fit ​​structure also enables the positioning of the support component 500, thereby improving the accuracy of the position of the temperature detection component 810 installed on the support component 500.

[0133] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0134] Support component 500 is an insulating component.

[0135] In this embodiment, the support component 500 is an insulating component, which reduces the probability of leakage between the temperature detection component 810 and the reflector 600, thereby improving the safety of the food warmer during use.

[0136] Specifically, the temperature detection component 810 is disposed on the support component 500, thereby creating a certain distance between the temperature detection component 810 and the reflector 600, which reduces the probability of leakage between the temperature detection component 810 and the reflector 600. Furthermore, by making the support component 500 an insulating component, the probability of leakage between the temperature detection component 810 and the reflector 600 can be further reduced.

[0137] Specifically, the support component 500 is made of high-temperature resistant plastic, rubber, wood, asbestos, or ceramic.

[0138] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0139] The heat-conducting coating 400 includes at least one of a graphene coating and a metal oxide coating.

[0140] In this embodiment, the heating coating 400 includes at least one of a graphene coating and a metal oxide coating. The heating coating 400 can be bonded to the second panel 300 via printing or vapor deposition, reducing installation difficulty and eliminating the need for an additional heating device, thus lowering costs. Since the graphene coating and metal oxide coating can be bonded to the second panel 300 via printing or vapor deposition, the axial height of the second panel 300 can be reduced, thereby reducing the axial height of the food warmer. This allows for a thinner and lighter design of the food warmer, making it easier for customers to use and improving its stability.

[0141] Specifically, the metal oxide can be indium tin oxide, or it can be an oxide including silver-palladium alloys or ruthenium.

[0142] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0143] The first panel 200 is a tempered glass panel.

[0144] The second panel 300 is a high borosilicate glass panel or a microcrystalline panel.

[0145] 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.

[0146] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0147] like Figure 2 As shown, the food warmer also includes a heating membrane 840, which is disposed on the side of the first panel 200 near the housing 100.

[0148] In this embodiment, the food warming board also includes a heating wire membrane 840, which is disposed on the side of the first panel 200 near the housing 100, thereby keeping the food placed on the first panel 200 warm.

[0149] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0150] The reflector 600 includes a cover body and a flange, the flange being arranged around the cover body and overlapping the support.

[0151] The flange is arranged around the cover body and overlaps the bracket, so that the bracket can support the stress position of the reflector 600, thereby improving the support effect of the bracket on the reflector 600.

[0152] like Figure 3 and Figure 2 As shown, the first panel 200 is provided with a third mounting opening, and the flange is arranged around the third mounting opening and adhered to the first panel 200; the second panel 300 is provided at the third mounting opening and is located on the flange.

[0153] The flange is arranged around the third mounting port and is bonded to the first panel 200. The second panel 300 is located at the third mounting port and is located on the flange. The first panel 200 and the second panel 300 are then installed and fixed by the flange of the reflector 600, and the surfaces of the first panel 200 and the second panel 300 are smoothly transitioned, making the surfaces of the first panel 200 and the second panel 300 more complete.

[0154] Furthermore, the flange is bonded to the back of the first panel 200 using high-temperature adhesive.

[0155] Furthermore, such as Figure 1 Figure 5 Figure 6 Figure 5 As shown, the first panel 200 is provided with a control area 870.

[0156] Furthermore, 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, which is 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 board can be improved, allowing customers to choose different panels for heating according to their actual needs and enriching the heat preservation effect of the warming board. Simultaneously, by attaching the heating coating 400 to the second panel 300, heating of the second panel 300 area can be achieved through the heating coating 400, which can increase the heating temperature of the first panel 200, simplify the heating structure, reduce the structural complexity of the warming board, improve assembly efficiency, and reduce the production cost of the warming board. Using the heating coating 400 to heat the second panel 300 can reduce the weight and axial height of the warming board, thereby achieving a thinner and lighter design for easier customer use. 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, enriching the functionality of the warming board and meeting different customer heating needs.

[0157] Furthermore, the heating coating 400 can be applied to the second panel 300 through printing or vapor deposition processes, simplifying the operation steps and reducing the difficulty of operation.

[0158] Furthermore, since the heating coating 400 occupies less space, the axial height of the warming board can be reduced. After placing the tableware on the warming board, the stability of the tableware can be improved by reducing the axial height, thereby enhancing the structural stability of the warming board and making it easier for daily use.

[0159] Furthermore, by setting different heating limits for the first panel 200 and the second panel 300, and with the second temperature value being greater than the first temperature value, the second panel 300 can heat and keep the tableware warm at a medium temperature, thereby improving the heating efficiency of the warming plate and enriching its heat preservation function.

[0160] Specifically, when using the food warmer, since the maximum temperature of the second panel 300 is greater than that of the first panel 200, customers can use the first panel 200 to keep the food warm, or use the second panel 300 to reheat cold dishes, thus improving heating efficiency.

[0161] Furthermore, the second panel 300 can be heated to a second temperature value, which is greater than or equal to 140 degrees Celsius. This allows the heat emitted by the second panel 300 to reheat cold food in the tableware, enriching the functionality of the warming plate and meeting diverse customer heating needs. Simultaneously, a second temperature value of less than or equal to 600 degrees Celsius ensures heating efficiency while reducing energy consumption and lowering the high-temperature resistance requirements of the second panel 300, thus saving costs.

[0162] Furthermore, the food warmer also includes a third panel, which can be heated to a third temperature value. The second temperature value is lower than the third temperature value. Food can be cooked and heated through the third panel. By simultaneously setting different temperature values ​​for the first panel 200, the second panel 300, and the third panel, different heat preservation and heating needs of users can be met.

[0163] The third panel is a microcrystalline panel. Since the third temperature value generated at the third panel is greater than the first and second temperature values, the third panel is a high-temperature area. Therefore, setting the third panel as a microcrystalline panel can help it resist high temperatures and improve its durability.

[0164] Since the first panel 200 is at the first temperature value, which is lower than the third and second temperature values, it is considered a low-temperature zone. Therefore, using tempered glass for the first panel 200 ensures durability while reducing costs. Since the second panel 300 is in the medium-temperature zone, using high-borosilicate glass or microcrystalline glass can improve its high-temperature resistance and durability.

[0165] Furthermore, there are multiple second panels 300. The maximum temperature that can be generated at the second panel 300 is a second temperature value, which 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 food warming board. By arranging multiple second panels 300 around the circumference of the first panel 200, the heating efficiency of the food warming board can be improved, energy consumption can be reduced, and the user's needs can be met.

[0166] Furthermore, the food warming board also includes a heating plate, which is located inside the housing 100 and opposite to the third panel. The heating plate can heat the third panel to a third temperature value, thereby enabling the third panel to heat up and facilitating the food warming board to keep the food warm.

[0167] Since the third temperature value is greater than the second and first temperature values, the third panel is a high-temperature area. The heating element in the high-temperature heating area is the heating plate, which can be an electric ceramic cooktop plate or an induction cooktop plate.

[0168] Furthermore, the food warmer also includes an insulating layer, which is disposed between the heating coating 400 and the second panel 300, or on the side of the second panel 300 away from the heating coating 400. The insulating layer improves the insulation performance of the second panel 300. When the food warmer is in operation, the second panel 300 is heated. By adding an insulating layer to the second panel 300, the high temperature can be prevented from affecting the insulation performance of the second panel 300, improving its durability and reducing its production cost.
