Description

Technical Field

[0001] This utility model relates to the field of cooking utensils technology, and more specifically, to a food warmer. Background Technology

[0002] Currently, food warming boards are equipped with heating wires that can heat the food placed on them. However, the heating wires have a low heating temperature and low heat transfer efficiency between them and the surface of the food warming board, resulting in significant heat loss. Consequently, the food warming board has a poor ability to reheat food that is already at a low temperature.

[0003] In related technologies, to improve the ability of a food warmer to reheat food at lower temperatures, a high-temperature panel is installed on the main panel of the warmer. This high-temperature panel has a heating coating with a high heating temperature, and a reflector is placed over the heating coating to concentrate heat. However, when the high-temperature panel is subjected to pressure, the reflector may detach, thus reducing the stability of the reflector during the use of the warmer. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this utility model proposes a food warming board.

[0006] In view of the above, the first aspect of this utility model provides a food warmer, including a shell, a first panel, a second panel, a heating coating, a bracket, and a reflector. The shell has a mounting cavity with an opening on at least one side; the first panel covers the opening and is connected to the shell; the second panel is arranged side by side with the first panel; the heating coating is disposed on the second panel; the bracket is disposed in the mounting cavity and abuts against the shell; the reflector is disposed on the bracket and covers the heating coating.

[0007] The food warmer provided in this application includes a shell, a first panel, and a second panel, which are arranged side by side for placing food. Both the first and second panels are disposed on the shell, thereby supporting the first and second panels. The food warmer also includes a heating coating disposed on the second panel, which heats the food placed on the second panel, thereby improving the heating effect of the food warmer.

[0008] The food warmer also includes a support frame and a reflector. The reflector covers the heating coating. The heat generated by the heating coating is transferred to the reflector and then reflected to the second panel, reducing heat loss from the heating coating and thus improving the heat transfer efficiency between the heating coating and the second panel. Furthermore, the reflector provides insulation and heat retention, saving on the cost of the food warmer and simplifying its structure.

[0009] The bracket is set inside the housing, and the reflector is set on the bracket. The bracket supports the reflector. When the second panel is subjected to a certain pressure, the pressure is transmitted from the second panel to the reflector, and then from the reflector to the bracket. The bracket then transmits the pressure to the housing, thereby reducing the probability of the bracket falling off under pressure and improving the stability of the reflector during the use of the food warmer.

[0010] Furthermore, the reflector is supported by a bracket, which also provides some heat insulation, reducing the heat transferred from the reflector to the housing. This lowers the probability of damage to the housing caused by heat generated by the heating coating, further improving the stability of the food warmer during operation. The bracket also prevents heat generated by the heating coating from escaping into the mounting cavity, allowing more heat to be transferred to the second panel, improving the heat transfer efficiency between the heating coating and the second panel, and further enhancing the food warmer's heating effect.

[0011] Furthermore, a heating coating is printed on the back of the second panel to increase the maximum heating temperature of the warming plate.

[0012] After the heating coating is fixed, it is connected to an electrode. The electrode is welded and fixed to the back of the second panel. The electrode can be a lead wire or a connector terminal.

[0013] Furthermore, the second panel can achieve a heating effect of 160 degrees Celsius to 400 degrees Celsius, and compared with the heating solution of electric ceramic stove, it has lower cost, simpler structure, and thinner product thickness.

[0014] Furthermore, the first panel has a control area.

[0015] In addition, the food warming board in the above-mentioned technical solution provided by this utility model may also have the following additional technical features:

[0016] In some technical solutions of this utility model, optionally, the bracket includes a support part and a support leg; the support part is arranged around the reflector, and the reflector overlaps the support part; the support leg is connected to the support part and abuts against the bottom wall of the mounting cavity.

[0017] In this technical solution, the bracket includes a support part and a support leg. The support part can support the reflector. One end of the support leg abuts against the bottom wall of the mounting cavity, and the other end is connected to the support part, thereby supporting the support part and further improving the stability of the bracket, and thus improving the stability of the reflector.

[0018] Furthermore, the support leg can be a single, integral component, extending in the same way as the support section.

[0019] There can also be multiple support legs, which are arranged at intervals along the circumference of the support.

[0020] The support legs can be fixed to the housing with screws or glued to the bottom wall of the mounting cavity.

[0021] Furthermore, the support leg and the support part can be an integral structure, the bracket can be a high-temperature resistant plastic part, or the bracket can be a stamped sheet metal part.

[0022] The support leg and the support part can also be a separate structure, with the support leg and the support part being separately machined structural components, and the support leg being assembled into the support part.

[0023] Optionally, in some technical solutions of this utility model, the reflector is provided with a first mounting port, and the bracket also includes a mounting part, which is connected to the support part and is located at the first mounting port.

[0024] In this technical solution, the reflector is provided with a first mounting port, and the bracket also includes a mounting part. The mounting part is connected to the support part and is located at the first mounting port. The reflector cooperates with the mounting part through the first mounting port to achieve the limiting between the bracket and the reflector. During the movement of the food warming board, the probability of the bracket deviating from the initial position is reduced, further improving the stability of the bracket during the use of the food warming board, and improving the effectiveness of the bracket in supporting the reflector.

[0025] In some technical solutions of this utility model, optionally, the shape of the first mounting opening matches the shape of the outer peripheral edge of the mounting part.

[0027] Optionally, in some technical solutions of this utility model, the food warmer also includes a temperature detection component, which is disposed in the mounting part and located in the cavity between the reflector and the heating coating.

[0028] In this technical solution, the temperature detection component is set in the mounting part and located in the cavity between the reflector and the heating coating. While ensuring that the temperature detection component can detect the temperature of the heating coating, the mounting part supports the temperature detection component, thereby simplifying the structure of the warming plate and reducing the assembly difficulty of the warming plate.

[0029] Optionally, in some technical solutions of this utility model, a buckle is provided on the side of the mounting part near the heating coating; the temperature detection component includes a temperature sensor, which is snapped into the buckle.

[0030] In this technical solution, the mounting section is equipped with a snap-fit ​​mechanism. The temperature sensor is snapped into the snap-fit, which limits the movement of the temperature sensor, improving its stability during use on the food warmer and thus enhancing the accuracy of the temperature detected. Furthermore, by limiting the temperature sensor through the snap-fit, assembly of the temperature sensor is achieved simply by installing it into the snap-fit, simplifying the assembly process, reducing assembly difficulty, and improving assembly efficiency.

[0031] Furthermore, the buckle includes a first engaging portion and a second engaging portion. The first end of both the first and second engaging portions are connected to the mounting portion. The second ends of both the first and second engaging portions are free ends. A gap exists between the first and second engaging portions. Each of the second ends of both the first and second engaging portions has a protruding latch. The temperature sensor is installed within the gap between the first and second engaging portions, located between the latch and the mounting portion. The first and second engaging portions cooperate to secure the temperature sensor.

[0032] Optionally, in some technical solutions of this utility model, the temperature sensing end of the temperature sensor abuts against the heating coating.

[0033] In this technical solution, the temperature sensing end of the temperature sensor is in contact with the heating coating, which further improves the accuracy of the temperature sensor in detecting the temperature of the heating coating.

[0034] Optionally, in some technical solutions of this utility model, the mounting part is provided with a second mounting port; the temperature detection component includes a temperature limiter, which is disposed at the second mounting port.

[0035] In this technical solution, the installation part is provided with a second installation port, and the temperature limiter is set at the second installation port. When the temperature of the heating coating is too high or out of control, the temperature limiter controls the heating coating to cut off the power, and the heating coating stops heating. This reduces the probability of the second panel continuing to heat up after the temperature sensor fails, thus causing safety hazards and improving the safety of the food warmer during operation.

[0036] Furthermore, the temperature limiter is provided with a limiting part, which fits against the mounting part, and a screw passes through the limiting part and is screwed onto the mounting part.

[0037] In some technical solutions of this utility model, optionally, the mounting part is provided with a wire hole, which passes through the mounting part along the height direction of the warming plate; the warming plate also includes a control board and a cable, the control board is disposed in the housing, the cable passes through the wire hole, one end of the cable is connected to the control board, and the other end is connected to the heating coating.

[0038] In this technical solution, one end of the cable is connected to the control board, and the other end is connected to the heating coating. The control board can control the working status of the heating coating through the cable. The mounting part is provided with a cable passage hole, through which the cable is passed. One end of the cable is connected to the control board, and the other end is connected to the heating coating, thereby realizing the wiring of the heating coating and avoiding the cable passing through the edge of the reflector, reducing the probability of the cable being damaged by the edge of the reflector, and further improving the stability of the food warming board during use.

[0039] Furthermore, the temperature sensor detects the operating temperature of the second panel or the heating coating and feeds the operating temperature back to the control board, which controls the power supply to the heating coating to control the temperature of the second panel.

[0040] The temperature limiter is installed on the cable, which can control the working status of the heated coating through the cable.

[0041] Optionally, in some technical solutions of this utility model, the bracket further includes a connecting part, which is arranged along the wall surface of the reflector away from the heating coating. One end of the connecting part is connected to the support part, and the other end is connected to the mounting part.

[0042] In this technical solution, the support portion supports the mounting portion through the connecting portion, thereby improving the stability of the mounting portion. Furthermore, the connecting portion is arranged along the wall surface of the reflector away from the heating coating, and it also supports the reflector, further enhancing its stability.

[0043] Optionally, in some technical solutions of this utility model, the reflector includes a cover body and a flange, the flange being arranged around the cover body and overlapping the support.

[0044] In this technical solution, the flange is arranged around the cover and overlaps the bracket, so that the bracket can support the stress position of the reflector, thereby improving the support effect of the bracket on the reflector.

[0045] Optionally, in some technical solutions of this utility model, the first panel is provided with a third mounting opening, and the flange is arranged around the third mounting opening and adhered to the first panel; the second panel is provided at the third mounting opening and is provided on the flange.

[0046] In this technical solution, the flange is arranged around the third mounting port and is bonded to the first panel. The second panel is set at the third mounting port and is set on the flange. The first panel and the second panel are then installed and fixed by the flange of the reflector, and the surfaces of the first panel and the second panel are smoothly transitioned, making the surfaces of the first panel and the second panel more complete.

[0047] Furthermore, the flange is bonded to the back of the first panel using high-temperature adhesive.

[0048] In some technical solutions of this utility model, the heating coating may optionally include at least one of graphene coating and metal oxide coating.

[0049] In this technical solution, the heating coating includes at least one of a graphene coating and a metal oxide coating. The heating coating can be adhered 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 adhered 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 food warmer. This allows for a thinner and lighter design of the food warmer, making it easier for users to use and improving its stability.

[0050] Specifically, the metal oxide can be indium tin oxide, or it can be an oxide including silver-palladium alloys or ruthenium.

[0051] In some technical solutions of this utility model, the first panel may be a tempered glass panel; and / or the second panel may be a borosilicate glass panel or a microcrystalline panel.

Detailed Implementation

[0065] 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.

[0066] 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.

[0067] The following reference Figures 1 to 6 This invention describes a food warmer according to some embodiments of the present invention.

[0068] In one embodiment of this utility model, such as Figure 1 and Figure 2As shown, a food warmer is provided, including a housing 100, a first panel 200, a second panel 300, a heating coating 400, a support 500, and a reflector 600. The housing 100 has a mounting cavity 110 with an opening 120 on at least one side; the first panel 200 covers the opening 120 and is connected to the housing 100; the second panel 300 is arranged side by side with the first panel 200; the heating coating 400 is disposed on the second panel 300; the support 500 is disposed in the mounting cavity 110 and abuts against the housing 100; the reflector 600 is disposed on the support 500 and covers the heating coating 400.

[0069] In this embodiment, the food warmer includes a housing 100, a first panel 200, and a second panel 300. The first panel 200 and the second panel 300 are arranged side by side for placing food. Both the first panel 200 and the second panel 300 are disposed on the housing 100, thereby supporting the first panel 200 and the second panel 300. The food warmer also includes a heating coating 400, which is disposed on the second panel 300. The heating coating 400 can heat the food placed on the second panel 300, thereby improving the heating effect of the food warmer.

[0070] The food warmer also includes a support 500 and a reflector 600. The reflector 600 covers the heating coating 400. Heat generated by the heating coating 400 is transferred to the reflector 600 and then reflected back to the second panel 300, reducing heat loss from the heating coating 400 and thus improving heat transfer efficiency between the heating coating 400 and the second panel 300. Furthermore, the reflector 600 provides heat insulation and heat concentration, saving on the cost of the food warmer and simplifying its structure.

[0071] The bracket 500 is disposed inside the housing 100, and the reflector 600 is disposed on the bracket 500. The bracket 500 supports the reflector 600. When the second panel 300 is subjected to a certain pressure, the pressure is transmitted from the second panel 300 to the reflector 600, and then from the reflector 600 to the bracket 500. The bracket 500 then transmits the pressure to the housing 100, thereby reducing the probability of the bracket 500 falling off under pressure and improving the stability of the reflector 600 during the use of the food warmer.

[0072] Furthermore, the reflector 600 is supported by the bracket 500, which also provides some heat insulation, reducing the heat transferred from the reflector 600 to the housing 100. This reduces the probability of damage to the housing 100 due to the heat generated by the heating coating 400, further improving the stability of the food warmer during operation. The bracket 500 also prevents the heat generated by the heating coating 400 from dissipating into the mounting cavity 110, allowing more heat to be transferred to the second panel 300, improving the heat transfer efficiency between the heating coating 400 and the second panel 300, and further enhancing the food warmer's heating effect.

[0073] Furthermore, a heating coating 400 is printed on the back of the second panel 300 to increase the maximum heating temperature of the warming plate.

[0074] After the heating coating 400 is fixed, it is also connected to an electrode. The electrode is welded and fixed to the back of the second panel 300. The electrode can be a lead wire or a connector terminal.

[0075] Furthermore, the second panel 300 can achieve a heating effect of 160 degrees Celsius to 400 degrees Celsius, and compared with the heating solution of electric ceramic stove, it has lower cost, simpler structure, and thinner product thickness.

[0076] Furthermore, the first panel 200 is provided with a control area.

[0079] In this embodiment, the bracket 500 includes a support portion 510 and a support leg 520. The support portion 510 can support the reflector 600. One end of the support leg 520 abuts against the bottom wall of the mounting cavity 110, and the other end is connected to the support portion 510, thereby supporting the support portion 510 and further improving the stability of the bracket 500, thereby improving the stability of the reflector 600.

[0080] Furthermore, the support leg 520 can be a single integral component, extending in the same way as the support portion 510.

[0081] There may be multiple support legs 520, which are arranged at intervals along the circumference of the support portion 510.

[0082] The support leg 520 can be fixed to the housing 100 with screws or glued to the bottom wall of the mounting cavity 110.

During the movement of the food warming board, the probability of the bracket 500 deviating from the initial position is reduced, further improving the stability of the bracket 500 during the use of the food warming board, and improving the effectiveness of the bracket 500 in supporting the reflector 600.

[0092] like Figure 1 and Figure 3As shown, the food warmer also includes a temperature detection component 810, which is disposed in the mounting part 530 and located in the cavity between the reflector 600 and the heating coating 400.

[0093] In this embodiment, the temperature detection component 810 is disposed in the mounting part 530 and located in the cavity between the reflector 600 and the heating coating 400. While ensuring that the temperature detection component 810 can detect the temperature of the heating coating 400, the mounting part 530 supports the temperature detection component 810, thereby simplifying the structure of the warming plate and reducing the assembly difficulty of the warming plate.

[0094] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

The buckle 532 can limit the temperature sensor 812, improve the stability of the temperature sensor 812 during use on the food warmer, and thus improve the accuracy of the temperature detected by the temperature sensor 812. Furthermore, by limiting the temperature sensor 812 through the buckle 532, during assembly, the temperature sensor 812 is installed into the buckle 532, thus achieving structural assembly of the temperature sensor 812, simplifying the assembly process, reducing the assembly difficulty of the temperature sensor 812, and improving the assembly efficiency of the temperature sensor 812.

[0097] Furthermore, the latch 532 includes a first latching portion and a second latching portion. The first end of both the first and second latching portions are connected to the mounting portion 530. The second ends of both the first and second latching portions are free ends. A gap exists between the first and second latching portions. Both the second ends of the first and second latching portions are provided with protruding fastening positions. The temperature sensor 812 is installed within the gap between the first and second latching portions, located between the fastening positions and the mounting portion 530.

One end of the cable 860 is connected to the control board 850, and the other end is connected to the heating coating 400. This enables the wiring of the cable 860 to the heating coating 400, avoids the cable 860 passing through the edge of the reflector 600, reduces the probability of the edge of the reflector 600 damaging the cable 860, and further improves the stability of the food warmer during use.

One end of the connecting part 540 is connected to the support part 510, and the other end is connected to the mounting part 530.

[0112] In this embodiment, the support portion 510 supports the mounting portion 530 through the connecting portion 540, thereby improving the stability of the mounting portion 530. Furthermore, the connecting portion 540 is arranged along the wall surface of the reflector 600 on the side away from the heating coating 400, and the connecting portion 540 can also support the reflector 600, further improving the stability of the reflector 600.

[0113] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0114] like Figure 1 and Figure 2 As shown, the reflector 600 includes a cover 620 and a flange 630. The flange 630 is arranged around the cover 620 and overlaps the bracket 500.

[0115] In this embodiment, the flange 630 is arranged around the cover 620 and overlaps the bracket 500, so that the bracket 500 can support the stress position of the reflector 600, thereby improving the support effect of the bracket 500 on the reflector 600.

[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 , Figure 4 and Figure 5 As shown, the first panel 200 is provided with a third mounting opening 210, and the flange 630 is arranged around the third mounting opening 210 and adhered to the first panel 200; the second panel 300 is provided at the third mounting opening 210 and is provided on the flange 630.

[0118] In this embodiment, the flange 630 is arranged around the third mounting opening 210 and is bonded to the first panel 200. The second panel 300 is disposed in the third mounting opening 210 and on the flange 630. The first panel 200 and the second panel 300 are then installed and fixed by the flange 630 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.

[0119] Furthermore, the flange 630 is bonded to the back of the first panel 200 using high-temperature adhesive.

[0120] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0121] The heat-conducting coating 400 includes at least one of a graphene coating and a metal oxide coating.

[0122] 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 users to use and improving its stability.

[0123] Specifically, the metal oxide can be indium tin oxide, or it can be an oxide including silver-palladium alloys or ruthenium.

[0124] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0125] The first panel 200 is a tempered glass panel; and / or the second panel 300 is a borosilicate glass panel or a microcrystalline panel.

[0126] 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.

[0127] 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 users to choose different panels for heating according to 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 user convenience. 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 heating needs of users.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] Specifically, when using the food warmer, since the maximum temperature of the second panel 300 is greater than that of the first panel 200, users can keep food warm using the first panel 200 or reheat cold dishes using the second panel 300, thus improving heating efficiency.

[0132] 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 different user 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] Furthermore, the food warming board also includes a heating plate, which is located inside the mounting cavity 110 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.

[0138] 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.

[0139] Furthermore, such as Figure 6 As shown, the food warming board also includes an insulating layer 830, 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 830 improves the insulation effect of the second panel 300. When the food warming board is in operation, the second panel 300 is heated. By adding the insulating layer 830 to the second panel 300, the high temperature can be prevented from affecting the insulation effect of the second panel 300, improving its durability and reducing its production cost.

[0140] This embodiment provides a food warmer, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0141] like Figure 1 As shown, the food warming board also includes a heating membrane 840, which is disposed on the side of the first panel 200 near the mounting cavity 110.

[0142] In this embodiment, the food warming board also includes a heating film 840, which is disposed on the side of the first panel 200 near the mounting cavity 110, thereby keeping the food placed on the first panel 200 warm through the heating film.
