Description

Technical Field

[0001] This utility model relates to the field of food warming board technology, specifically to a panel assembly and a food warming board. Background Technology

[0002] Currently, in related technologies, food warmers have a panel with a heating area and a heat-preserving area. Heating wires are located below the heat-preserving area. When the food warmer is in operation, the heat generated by the heating wires is transferred to the tableware on the warmer through the panel, thus keeping the tableware warm. However, because the heating wires have a relatively low heating temperature, the food warmer is not very effective at heating cold food in the tableware, affecting user experience. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this utility model proposes a panel assembly.

[0005] The second aspect of this utility model proposes a food warming board.

[0006] In view of the above, the first aspect of the present invention provides a panel assembly for a food warming board. The panel assembly includes a first panel, a second panel, and a heating coating. The first panel is provided with a mounting hole, the second panel is disposed at the mounting hole, and the heating coating is attached to the second panel. When the food warming board is working, the first panel can be heated to a first temperature value, and the second panel can be heated to a second temperature value, wherein the second temperature value is greater than the first temperature value.

[0007] This application provides a panel assembly for a food warmer. Customers can place tableware on the panel assembly for support and heat retention, improving product performance. The panel assembly includes a first panel, a second panel, and a heating coating. By using a multi-panel structure, the assembly achieves multi-functional heating, enhancing the food warmer's practicality. The first panel has mounting holes, and the second panel is positioned at these holes. The heating coating is adhered to the second panel. When the food warmer is in operation, the first panel heats to a first temperature value, and the second panel heats to a second temperature value, which is higher than the first. By setting different heating limits for the first and second panels, the functionality of the panel assembly is enhanced, allowing customers to select different panels for heating based on their needs, thus enriching the food warmer's heat retention. Simultaneously, by adhering the heating coating to the second panel, heating of the second panel area is achieved through the coating, increasing the heating temperature of the first panel. This also simplifies the heating structure, reduces the structural complexity of the food warmer, improves assembly efficiency, and lowers production costs. By applying a heating coating to heat the second panel, the weight and axial height of the panel assembly can be reduced, thereby enabling a thinner and lighter design for the food warmer, making it easier for customers to use.

[0008] By setting a second temperature value greater than the first temperature value, the heat emitted by the second panel can be used to reheat cold food in the tableware, enriching the functionality of the warming plate and meeting different heating needs of customers.

[0009] Specifically, when using the food warmer, since the maximum temperature of the second panel is greater than that of the first panel, customers can use the first panel to keep the food warm or the second panel to reheat cold dishes, thus improving heating efficiency.

[0010] Furthermore, the heating coating can be applied to the second panel through printing or vapor deposition processes, simplifying the operation steps and reducing the difficulty of operation.

[0011] Furthermore, since the heating coating 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.

[0012] Furthermore, by setting different heating limits for the first and second panels, and with the second temperature value being greater than the first temperature value, the second panel 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.

[0013] In addition, the panel assembly in the above-mentioned technical solution provided by this utility model may also have the following additional technical features:

[0014] In some technical solutions of this utility model, optionally, the second temperature value is greater than or equal to 140 degrees Celsius and less than or equal to 600 degrees Celsius.

[0015] In this technical solution, since the second panel can be heated to a second temperature value, which is greater than or equal to 140 degrees Celsius, the heat emitted by the second panel can be used to reheat cold food in the tableware, enriching the functionality of the warming plate and meeting different heating needs of customers. At the same time, a second temperature value of less than or equal to 600 degrees Celsius can reduce energy consumption while ensuring heating efficiency, and also reduce the high temperature resistance requirements of the second panel, saving costs.

[0016] Optionally, in some technical solutions of this utility model, the panel assembly further includes a reflector, which is disposed at the mounting hole and overlaps the edge of the mounting hole, and the reflector has a groove; a second panel is disposed on the reflector and covers the groove opening.

[0017] In this technical solution, the panel assembly also includes a reflector, which is located at the mounting hole and overlaps the edge of the mounting hole. The reflector has a groove. A second panel is located on the reflector and covers the opening of the groove. Since the heating coating is attached to the second panel, the reflector at the mounting hole can concentrate the heat radiated by the heating coating, improving the heating efficiency of the second panel. At the same time, because the reflector also overlaps the edge of the mounting hole, it can protect the internal structure of the cooking plate. As the heat radiated by the heating coating is concentrated and reflected onto the second panel by the reflector, the high temperature generated by the heating coating can be prevented from affecting the cooking plate, thus improving the durability of the cooking plate.

[0018] Optionally, in some technical solutions of this utility model, the panel assembly further includes an insulating layer, which is disposed between the heating coating and the second panel, or the insulating layer is disposed on the side of the second panel away from the heating coating.

[0019] In this technical solution, the panel assembly also includes an insulating layer, which is disposed between the heating coating and the second panel, or on the side of the second panel away from the heating coating. The insulating layer improves the insulation performance of the panel assembly. When the food warmer is in operation, the second panel is heated. By adding an insulating layer to the second panel, the high temperature can be prevented from affecting its insulation performance, thus improving the durability of the panel assembly and reducing the production cost of the second panel.

[0020] Optionally, in some technical solutions of this utility model, the panel assembly further includes a third panel, which is disposed inside the first panel; wherein the third panel can be heated to a third temperature value, and the second temperature value is lower than the third temperature value.

[0021] In this technical solution, the panel assembly also includes a third panel, which is located inside the first panel. This third panel improves the support of the panel assembly, allowing customers to place tableware on the warming plate's panel assembly for better support and heat retention, thus enhancing product performance. The third panel can heat to a third temperature value, since the second temperature value is lower than the third. Food can be cooked and heated using the third panel. By simultaneously setting different temperature values ​​for the first, second, and third panels, different heat retention and heating needs of users can be met.

[0022] Optionally, in some technical solutions of this utility model, the panel assembly further includes a bracket, which is arranged around the third panel and overlaps the first panel.

[0023] In this technical solution, the panel assembly also includes a bracket, which is arranged around the third panel and overlaps the first panel. This improves the stability of the panel assembly and also facilitates the assembly of the third panel and the first panel.

[0024] In some technical solutions of this utility model, the heating coating may optionally include at least one of graphene coating and metal oxide coating.

[0025] In this technical solution, the heating coating includes at least one of graphene coating and metal oxide coating. The heating coating can be bonded to the second panel 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 via printing or vapor deposition, the axial height of the second panel can be reduced, thereby reducing the axial height of the panel assembly. This allows for a thinner and lighter design of the food warmer, making it easier for customers to use and improving the stability of the food warmer.

[0026] In some technical solutions of this utility model, optionally, the third panel is a microcrystalline panel; and / or the first panel is a tempered glass panel; and / or the second panel is a borosilicate glass panel or a microcrystalline panel.

[0027] In this technical solution, 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 play a role in high temperature resistance and improve the durability of the third panel.

[0028] Alternatively, the first panel can be made of tempered glass. Since the first panel is located at the first temperature value, which is lower than the third and second temperature values, it falls within the low-temperature zone. Therefore, using tempered glass for the first panel ensures durability while reducing costs. The second panel can also be made of borosilicate glass or a microcrystalline panel. Since the second panel is in the medium-temperature zone, using borosilicate glass or a microcrystalline panel can improve its high-temperature resistance and durability.

[0029] In some technical solutions of this utility model, optionally, there are multiple second panels, and the multiple second panels are arranged circumferentially along the first panel.

[0030] In this technical solution, there are multiple second panels arranged circumferentially around the first panel, which improves the heating effect of the second panels. The maximum temperature that can be generated at the second panel is a second temperature value, which is greater than the first temperature value but less than the third temperature value. Therefore, the second panels can provide medium-temperature heating for the food warming board. By arranging multiple second panels circumferentially around the first panel, the heating efficiency of the food warming board can be improved, energy consumption can be reduced, and user needs can be met.

[0031] The second aspect of this utility model provides a food warming board, including a panel assembly as described in any of the above technical solutions.

[0032] The present application provides a food warmer, comprising a panel assembly as described in any of the above-described technical solutions. Therefore, this food warmer possesses all the beneficial effects of the panel assembly as described in any of the above-described technical solutions.

[0033] Optionally, in some technical solutions of this utility model, the food warmer also includes a base, a chassis, and a driving component. The chassis is disposed on the base, the panel assembly is disposed on the chassis, and the driving component is disposed on the base, capable of driving the chassis and the panel assembly to rotate relative to the base.

[0034] In this technical solution, the food warming board also includes a base, a chassis, and a drive component. The chassis is set on the base, and the cooperation between the chassis and the base improves the stability of the food warming board. The panel assembly is set on the chassis, and the drive component is set on the base, which reduces assembly difficulty and improves the production efficiency of the food warming board. The drive component can drive the chassis and panel assembly to rotate relative to the base, enabling the panel assembly to rotate for easy display or handling of dishes, and also achieving uniform heating, thus improving the working effect of the food warming board.

[0035] Optionally, in some technical solutions of this utility model, the food warming plate also includes a heating plate, which is disposed on the base and opposite to the third panel of the panel assembly, and is capable of heating the third panel to a third temperature value.

[0036] In this technical solution, the food warming board also includes a heating plate, which is set on the base 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 making it easier for the food warming board to keep the food warm.

[0037] Specifically, since the third temperature value is greater than the second and first temperature values, the third panel is a high-temperature area, and 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.

[0038] In some technical solutions of this utility model, optionally, the minimum distance between the edge of the heating coating and the edge of the heating plate is greater than or equal to 80 mm.

[0039] In this technical solution, the minimum distance between the edge of the heating coating and the edge of the heating plate is greater than or equal to 80 mm. Since a driving component is installed inside the food warmer and is located near the heating plate, limiting the minimum distance between the edge of the heating coating and the edge of the heating plate can prevent the high-temperature heat generated by the heating plate and heating coating from affecting the driving component, thereby improving the durability of the driving component and reducing the failure rate.

[0040] Since the minimum distance between the edge of the heating coating and the edge of the heating plate is greater than or equal to 80 mm, the drive component can be placed between the heating coating and the heating plate, thereby reducing the axial height of the warming plate, improving the stability of the warming plate, and preventing the plates from shaking when placed on the warming plate.

[0041] Specifically, the minimum distance between the edge of the heating coating and the edge of the heating plate can be H1, and the minimum distance H1 between the edge of the heating coating and the edge of the heating plate can be greater than or equal to 80 mm and less than or equal to 200 mm.

[0042] Specifically, the minimum distance H1 between the edge of the heating coating and the edge of the heating plate can be 80 mm, 100 mm, 120 mm, or 200 mm.

[0043] Optionally, in some technical solutions of this utility model, the food warmer also includes a heating wire membrane, which is disposed on the side of the first panel close to the substrate and is capable of heating the first panel to a first temperature value.

[0044] In this technical solution, the food warmer also includes a heating wire membrane, which can generate heat when electricity is applied. Since the heating wire membrane is located on the side of the first panel close to the substrate, it can heat the first panel to a first temperature value, thereby achieving heating of the first panel and making it convenient for users to use.

[0045] The first temperature value is lower than the second and third temperature values. Therefore, by setting a heating wire membrane, low-temperature heating can be achieved, reducing the energy consumption of the food warmer and enriching its usage.

[0046] In some technical solutions of this utility model, optionally, the minimum distance between the edge of the heating coating and the edge of the heating wire film is greater than or equal to 30 mm.

[0047] In this technical solution, the minimum distance between the edge of the heating coating and the edge of the heating wire film is greater than or equal to 30 mm. Since the maximum temperature of the second panel is greater than that of the first panel, the temperature generated by the heating coating is higher than that generated by the heating wire film. By limiting the minimum distance between the edges of the heating coating and the heating wire film, the high-temperature heat generated by the heating coating can be prevented from affecting the normal operation of the heating wire film. Simultaneously, the high temperature generated by the heating coating can be prevented from spreading and affecting the durability of the first panel. Limiting the minimum distance between the edges of the heating coating and the heating wire film to greater than or equal to 30 mm not only prevents the heat generated by the heating coating from damaging the heating wire film, but also improves the heating effect of the panel assembly, achieving layered heating. This allows for differentiation of the maximum heating temperature of different panels, facilitating user operation.

[0048] Specifically, the minimum distance between the edge of the heating coating and the edge of the heating wire membrane is H2, which is greater than or equal to 30 mm and less than 100 mm.

[0049] Specifically, the minimum distance H2 between the edge of the heating coating and the edge of the heating wire membrane can be 30 mm, 50 mm, 70 mm, or 100 mm.

Detailed Implementation

[0061] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0062] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0063] The following reference Figures 1 to 7 The present invention describes a panel assembly 100 and a food warmer 200 according to some embodiments of the present invention.

[0064] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the embodiment of this utility model, a panel assembly 100 is provided. The panel assembly 100 is used for a food warmer 200. The panel assembly 100 includes a first panel 120, a second panel 130, and a heating coating 132. The first panel 120 is provided with a mounting hole 122, the second panel 130 is disposed at the mounting hole 122, and the heating coating 132 is attached to the second panel 130. When the food warmer 200 is working, the first panel 120 can be heated to a first temperature value, and the second panel 130 can be heated to a second temperature value, the second temperature value being greater than the first temperature value.

[0065] This application provides a panel assembly 100 for use on a food warmer 200. Customers can place tableware on the panel assembly 100 of the food warmer 200 for easy support and heat preservation, thus improving product performance. The panel assembly 100 includes a first panel 120, a second panel 130, and a heating coating 132. By setting a multi-panel structure, the panel assembly 100 can achieve multi-functional heating, enhancing the practicality of the food warmer 200. The first panel 120 is arranged around a third panel 110, and the first panel 120 is provided with mounting holes 122. The second panel 130 is disposed at the mounting holes 122, and the heating coating 132 is adhered to the second panel 130. When the food warming board 200 is in operation, the first panel 120 can be heated to a first temperature value, and the second panel 130 can be heated to a second temperature value, which is higher than the first temperature value. By setting different heating limits for the first panel 120 and the second panel 130, the functionality of the panel assembly 100 can be improved, allowing customers to choose different panels for heating according to actual needs and enriching the heat preservation effect of the food warming board 200. Simultaneously, by attaching the heating coating 132 to the second panel 130, heating of the second panel 130 area can be achieved through the heating coating 132, which can increase the heating temperature of the first panel 120, simplify the heating structure, reduce the structural complexity of the food warming board 200, improve assembly efficiency, and reduce the production cost of the food warming board 200. By using the heating coating 132 to heat the second panel 130, the weight and axial height of the panel assembly 100 can be reduced, thereby achieving a thinner and lighter design for the food warming board 200, making it easier for customers to use.

[0066] By setting a second temperature value greater than the first temperature value, the heat emitted by the second panel 130 can be used to reheat cold food in the tableware, enriching the functionality of the warming plate 200 and meeting different heating needs of customers.

[0067] Specifically, when using the food warming board 200, since the extreme temperature of the second panel 130 is greater than that of the first panel 120, customers can keep food warm through the first panel 120 and reheat cold dishes through the second panel 130, thus improving heating efficiency.

[0068] Furthermore, since the heating coating 132 occupies a small space, the axial height of the warming plate 200 can be reduced. After placing the tableware on the warming plate 200, the stability of the tableware can be improved by reducing the axial height, thereby enhancing the structural stability of the warming plate 200 and making it easier for daily use.

[0069] Specifically, if Figure 1 , Figure 2 and Figure 6 As shown, a circuit board 260 is also provided in the food warming board 200. The circuit board 260 can control the heating temperature of the third panel 110, the first panel 120, and the second panel 130, thereby improving the working efficiency of the food warming board 200. In addition, a control component 270 can be additionally provided on the panel assembly 100. The control component 270 is electrically connected to the circuit board 260, and the customer can control the working temperature of the food warming board 200 through the control component 270 for customer convenience.

[0070] This embodiment provides a panel assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0071] The second temperature value is greater than or equal to 140 degrees Celsius and less than or equal to 600 degrees Celsius.

[0072] In this embodiment, since the second panel 130 can be heated to a second temperature value, which is greater than or equal to 140 degrees Celsius, the heat emitted by the second panel 130 can be used to reheat cold food in the tableware, enriching the functionality of the panel assembly 100 and meeting different heating needs of customers. Meanwhile, a second temperature value of less than or equal to 600 degrees Celsius can reduce energy consumption while ensuring heating efficiency, and also lower the high-temperature resistance requirements of the second panel 130, saving costs.

[0073] Specifically, the second temperature value can be 140 degrees Celsius, 300 degrees Celsius, 500 degrees Celsius, or 600 degrees Celsius. This embodiment provides a panel assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0074] like Figure 1 , Figure 4 and Figure 5 As shown, the panel assembly 100 also includes a reflector 140, which is disposed at the mounting hole 122 and overlaps the edge of the mounting hole 122. The reflector 140 has a groove 142. The second panel 130 is disposed on the reflector 140 and covers the slot 144 of the groove 142.

[0075] In this embodiment, the panel assembly 100 further includes a reflector 140, which is disposed at the mounting hole 122 and overlaps the edge of the mounting hole 122. The reflector 140 has a groove 142. The second panel 130 is disposed on the reflector 140 and covers the slot 144 of the groove 142. Since the heating coating 132 is attached to the second panel 130, the reflector 140 at the mounting hole 122 can concentrate the heat radiated by the heating coating 132, thereby improving the heating efficiency of the second panel 130. At the same time, since the reflector 140 also overlaps the edge of the mounting hole 122, it can protect the internal structure of the food warming board 200. Because the heat radiated by the heating coating 132 will be concentrated and reflected onto the second panel 130 by the reflector 140, the high temperature generated by the heating coating 132 can be prevented from affecting the food warming board 200, thereby improving the durability of the food warming board 200.

[0076] This embodiment provides a panel assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0077] The panel assembly 100 also includes an insulating layer 150, which is disposed between the heating coating 132 and the second panel 130, or on the side of the second panel 130 away from the heating coating 132.

[0078] In this embodiment, the panel assembly 100 further includes an insulating layer 150, which is disposed between the heating coating 132 and the second panel 130, or on the side of the second panel 130 away from the heating coating 132. The insulating layer 150 improves the insulation effect of the panel assembly 100. When the food warmer 200 is in operation, the second panel 130 is heated. By adding the insulating layer 150 to the second panel 130, the high temperature can be prevented from affecting the insulation effect of the second panel 130, improving the durability of the panel assembly 100 and reducing the production cost of the second panel 130.

[0079] The panel assembly 100 also includes a third panel 110, which is disposed inside the first panel 120; wherein the third panel 110 is capable of being heated to a third temperature value, the second temperature value being lower than the third temperature value.

[0080] In this embodiment, the panel assembly 100 further includes a third panel 110, which is disposed inside the first panel 120. The third panel 110 improves the support of the panel assembly 100, allowing customers to place tableware on the warming plate panel assembly 100 for support and heat preservation, thus enhancing product performance. The third panel 110 can be heated to a third temperature value, which is lower than the second temperature value. Food can be cooked and heated using the third panel 110. By simultaneously setting different temperature values ​​for the first panel 120, the second panel 130, and the third panel 110, different heat preservation and heating needs of users can be met.

[0081] Furthermore, by setting the heating limits of the third panel 110, the first panel 120, and the second panel 130 to be different, and the second temperature value being greater than the first temperature value and less than the third temperature value, the second panel 130 can heat and keep the tableware warm at a medium temperature, thereby improving the heating efficiency of the warming plate 200 and enriching the heat preservation function of the warming plate 200.

[0082] Specifically, the heating coating can be set to a medium temperature zone, that is, the second temperature value of the second panel 130 can be between 140 degrees Celsius and 250 degrees Celsius, which can be used to reheat cooked cold food; the first temperature value of the low temperature zone formed by the first panel 120 can be between 40 degrees Celsius and 140 degrees Celsius, which can keep hot food warm, reduce energy consumption and keep the food warm; the third temperature value of the high temperature zone at the third panel 110 can be between 250 degrees Celsius and 620 degrees Celsius, which can be used to cook food.

[0083] Specifically, the first temperature value can be 40 degrees Celsius, the first temperature value can be 60 degrees Celsius, the first temperature value can be 80 degrees Celsius, and the first temperature value can be 140 degrees Celsius.

[0084] Specifically, the third temperature value can be 250 degrees Celsius, the third temperature value can be 300 degrees Celsius, the third temperature value can be 350 degrees Celsius, and the third temperature value can be 620 degrees Celsius. Specifically, the second temperature value can be 140 degrees Celsius, the second temperature value can be 180 degrees Celsius, the second temperature value can be 220 degrees Celsius, and the second temperature value can be 250 degrees Celsius.

[0085] This embodiment provides a panel assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0086] The panel assembly 100 also includes a bracket 160, which is arranged around the third panel 110 and overlaps the first panel 120.

[0087] In this embodiment, the panel assembly 100 further includes a bracket 160, which is arranged around the third panel 110 and overlaps the first panel 120. This can improve the stability of the panel assembly 100 and also facilitate the assembly of the third panel 110 and the first panel 120.

[0088] This embodiment provides a panel assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0089] The heating coating 132 includes at least one of a graphene coating and a metal oxide coating.

[0090] In this embodiment, the heating coating 132 includes at least one of a graphene coating and a metal oxide coating. The heating coating 132 can be bonded to the second panel 130 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 130 via printing or vapor deposition, the axial height of the second panel 130 can be reduced, thereby reducing the axial height of the panel assembly 100. This allows for a thinner and lighter design of the food warmer 200, making it easier for customers to use and improving the stability of the food warmer 200.

[0091] This embodiment provides a panel assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0092] The third panel 110 is a microcrystalline panel; and / or the first panel 120 is a tempered glass panel; and / or the second panel 130 is a borosilicate glass panel or a microcrystalline panel.

[0093] In this embodiment, the third panel 110 is a microcrystalline panel. Since the third temperature value generated at the third panel 110 is greater than the first temperature value and the second temperature value, the third panel 110 is a high temperature area. Therefore, setting the third panel 110 as a microcrystalline panel can play a role in high temperature resistance and improve the durability of the third panel 110.

[0094] Alternatively, the first panel 120 can be made of tempered glass. Since the first panel 120 is located at the first temperature value, which is lower than the third and second temperature values, it is a low-temperature zone. Therefore, making the first panel 120 a tempered glass panel can ensure durability while reducing costs. Alternatively, the second panel 130 can be made of borosilicate glass or a microcrystalline panel. Since the second panel 130 is in a medium-temperature zone, using a borosilicate glass or microcrystalline panel can improve the high-temperature resistance of the second panel 130 and enhance its durability.

[0095] This embodiment provides a panel assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0096] There are multiple second panels 130, and the multiple second panels 130 are arranged around the first panel 120.

[0097] In this embodiment, there are multiple second panels 130 arranged circumferentially around the first panel 120, which improves the heating effect of the second panels 130. The maximum temperature that can be generated at the second panel 130 is a second temperature value, which is greater than the first temperature value but less than the third temperature value. Therefore, the second panel 130 can provide medium-temperature heating for the food warming board 200. By arranging multiple second panels 130 circumferentially around the first panel 120, the heating efficiency of the food warming board 200 can be improved, energy consumption can be reduced, and user needs can be met.

[0098] Specifically, the circumferential direction of the first panel 120 and the third panel 110 is direction F1.

[0099] In an embodiment of this utility model, a food warmer 200 is provided, including a panel assembly 100 as described in any of the above embodiments.

[0100] like Figure 1 and Figure 2 As shown, the food warmer 200 provided in this application includes a panel assembly 100 as described in any of the above embodiments. Therefore, this food warmer 200 possesses all the beneficial effects of the panel assembly 100 as described in any of the above embodiments.

[0101] This embodiment provides a food warming board 200, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0102] The food warmer 200 also includes a base 210, a chassis 220, and a drive component 230. The chassis 220 is disposed on the base 210, the panel assembly 100 is disposed on the chassis 220, and the drive component 230 is disposed on the base 210 and is capable of driving the chassis 220 and the panel assembly 100 to rotate relative to the base 210.

[0103] In this embodiment, the food warming board 200 also includes a base 210, a chassis 220, and a driving component 230. The chassis 220 is disposed on the base 210, and the stability of the food warming board 200 can be improved through the cooperation between the chassis 220 and the base 210. The panel assembly 100 is disposed on the chassis 220, and the driving component 230 is disposed on the base 210, which can reduce the assembly difficulty and improve the production efficiency of the food warming board 200. The driving component 230 can drive the chassis 220 and the panel assembly 100 to rotate relative to the base 210, which can realize the rotation of the panel assembly 100, making it easier to display or pick up dishes, and can also achieve uniform heating, improving the working effect of the food warming board 200.

[0104] This embodiment provides a food warming board 200, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0105] The food warmer 200 also includes a heating plate 240, which is disposed on the base 210 and opposite to the third panel 110 of the panel assembly 100, and is capable of heating the third panel 110 to a third temperature value.

[0106] In this embodiment, the food warming plate 200 also includes a heating plate 240, which is disposed on the base 210 and opposite to the third panel 110 of the panel assembly 100. The heating plate 240 can heat the third panel 110 to a third temperature value, thereby enabling the third panel 110 to heat up and making it easier for the food warming plate 200 to keep the food warm.

[0107] Specifically, since the third temperature value is greater than the second temperature value and the first temperature value, the third panel 110 is a high-temperature area, and the heating element in the high-temperature heating area is the heating plate 240, which can be an electric ceramic cooktop plate or an induction cooktop plate.

[0108] This embodiment provides a food warming board 200, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0109] The minimum distance between the edge of the heating coating 132 and the edge of the heating plate 240 is greater than or equal to 80 mm.

[0110] In this embodiment, the minimum distance between the edge of the heating coating 132 and the edge of the heating plate 240 is greater than or equal to 80 mm. Since a driving component 230 is provided inside the food warming plate 200 and is located near the heating plate 240, limiting the minimum distance between the edge of the heating coating 132 and the edge of the heating plate 240 avoids the impact of the high-temperature heat generated by the heating plate 240 and the heating coating 132 on the driving component 230, thereby improving the durability of the driving component 230 and reducing the failure rate.

[0111] Since the minimum distance between the edge of the heating coating 132 and the edge of the heating plate 240 is greater than or equal to 80 mm, the driving component 230 can be set between the heating coating 132 and the heating plate 240, thereby reducing the axial height of the warming plate 200, improving the stability of the warming plate 200, and preventing the plate from shaking when placed on the warming plate 200.

[0112] Specifically, the minimum distance between the edge of the heating coating 132 and the edge of the heating plate 240 can be H1. The minimum distance H1 between the edge of the heating coating 132 and the edge of the heating plate 240 can be greater than or equal to 80 mm and less than or equal to 200 mm.

[0113] Specifically, the minimum distance H1 between the edge of the heating coating 132 and the edge of the heating plate 240 can be 80 mm, 100 mm, 120 mm, or 200 mm.

[0114] This embodiment provides a food warming board 200, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0115] The food warmer 200 also includes a heating wire membrane 250, which is disposed on the side of the first panel 120 near the substrate 210 and is capable of heating the first panel 120 to a first temperature value.

[0116] In this embodiment, the food warmer 200 also includes a heating wire membrane 250, which can generate heat after being powered on. Since the heating wire membrane 250 is disposed on the side of the first panel 120 near the substrate 210, it can heat the first panel 120 to a first temperature value, thereby achieving heating of the first panel 120 and making it convenient for users to use.

[0117] The first temperature value is lower than the second and third temperature values. Therefore, by setting the heating wire membrane 250, low-temperature heating can be achieved, reducing the energy consumption of the food warmer 200 and enriching the usage effect of the food warmer 200.

[0118] This embodiment provides a food warming board 200, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0119] The minimum distance between the edge of the heating coating 132 and the edge of the heating wire membrane 250 is greater than or equal to 30 mm.

[0120] In this embodiment, the minimum distance between the edge of the heating coating 132 and the edge of the heating film 250 is greater than or equal to 30 mm. Since the maximum temperature of the second panel 130 is greater than the maximum temperature of the first panel 120, the temperature generated by the heating coating 132 is higher than the temperature generated by the heating film 250. By limiting the minimum distance between the edge of the heating coating 132 and the edge of the heating film 250, the high-temperature heat generated by the heating coating 132 can be prevented from affecting the normal operation of the heating film 250. Simultaneously, the high temperature generated by the heating coating 132 can be prevented from spreading and affecting the durability of the first panel 120. Limiting the minimum distance between the edge of the heating coating 132 and the edge of the heating film 250 to greater than or equal to 30 mm can prevent the heat generated by the heating coating 132 from damaging the heating film 250, while also improving the heating effect of the panel assembly 100, achieving layered heating, distinguishing the maximum heating temperature of different panels, and facilitating user operation.

[0121] Specifically, the minimum distance between the edge of the heating coating 132 and the edge of the heating wire membrane 250 is H2, which is greater than or equal to 30 mm and less than or equal to 100 mm.

[0122] Specifically, if Figure 7 As shown, the minimum distance H2 between the edge of the heating coating 132 and the edge of the heating wire membrane 250 can be 30 mm, 50 mm, 70 mm, or 100 mm.

[0123] Specifically, the second temperature value can be between 160 degrees Celsius and 400 degrees Celsius, and the third temperature value can be above 600 degrees Celsius.
