Description

Technical Field

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

[0002] Currently, in related technologies, electromagnetic food warmers, when powered on, can heat up cookware made of magnetic materials placed on them, thus heating and keeping food warm. However, when using cookware made of non-magnetic materials, the electromagnetic food warmer cannot heat or keep food warm, resulting in reduced utilization and impacting customer 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 food warming board.

[0005] In view of the above, the first aspect of the present invention provides a food warming board, including a support assembly, a panel assembly, a coil, and a heating coating. The panel assembly is disposed on the support assembly, and the panel assembly and the support assembly enclose an installation cavity. The panel assembly includes a first panel, the coil is disposed in the installation cavity and opposite to the first panel, and the heating coating is disposed on the first panel and located on the side of the first panel near the coil.

[0006] This application provides a food warmer, comprising a support assembly, a panel assembly, a coil, and a heating coating. The panel assembly is disposed within the support assembly, and the panel assembly and support assembly enclose a mounting cavity. The panel assembly includes a first panel, and the coil is disposed within the mounting cavity, opposite to the first panel. The heating coating is disposed on the first panel, located on the side of the first panel closest to the coil. By applying the heating coating, the heating coating can conduct electricity, thereby generating heat. The heat is then conducted through the first panel to heat and keep the cookware warm, improving heating efficiency. Simultaneously, using the heating coating as a heat source, the food warmer can heat cookware made of non-magnetic materials, enhancing its adaptability and practicality. Since the coil is disposed within the mounting cavity, opposite the first panel, it can also, when energized, heat magnetic cookware placed on the first panel through electromagnetic induction, thereby heating and keeping food warm. By simultaneously incorporating the coil and the heating coating, it is possible to heat and keep cookware of different materials, further enhancing the practicality of the food warmer.

[0007] Specifically, the combination of a coil and a heating coating enables the warming plate to operate in two modes. When heating cookware made of magnetic materials, the coil and heating coating work simultaneously to improve heating and heat retention efficiency. When heating cookware made of non-magnetic materials, the heating coating generates heat, enhancing the warming plate's adaptability and practicality.

[0008] Furthermore, the heating coating is located on the side of the first panel near the coil, ensuring direct heat transfer, reducing heat loss, and improving heating efficiency.

[0009] Specifically, by setting the heating device as a heating coating, the installation steps can be simplified, and the weight and axial height of the panel assembly can be reduced, thereby achieving a thinner and lighter design for the food warmer, making it easier for customers to use.

[0010] 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:

[0011] Optionally, in some technical solutions of this utility model, the food warmer also includes a temperature sensor, which is disposed on the side of the first panel near the coil and is capable of detecting the temperature of the first panel.

[0012] In this technical solution, the food warmer also includes a temperature sensor, which is located on the side of the first panel near the coil. The temperature sensor can detect the temperature of the first panel and ensure that the food warmer can maintain the set temperature range during operation, thereby improving the practicality of the food warmer.

[0013] Specifically, the temperature sensor can help the food warmer achieve energy-saving optimization. When the temperature of the first panel is detected to have reached or approached the set value, the food warmer can automatically adjust the heating power to reduce unnecessary energy consumption.

[0014] Optionally, in some technical solutions of this utility model, the heating coating has an installation port, through which the temperature sensor passes and contacts the first panel.

[0015] In this technical solution, an installation port is provided on the heating coating, which facilitates the insertion of a temperature sensor into the heating coating for easy assembly. Since the temperature sensor passes through the installation port and is in contact with the first panel, it can detect the operating temperature of the first panel, thus accurately reflecting the temperature status of the heating coating. By monitoring and feeding back temperature information in real time, the temperature sensor helps the control system achieve more precise temperature regulation, ensuring that the food warmer operates stably within the set temperature range.

[0016] Furthermore, the temperature sensor can directly contact the first panel, that is, the detection end of the temperature sensor is directly abutted against the first panel, which can improve the detection accuracy.

[0017] Furthermore, the temperature sensor can be in indirect contact with the first panel, that is, a heat conductor is set between the temperature sensor and the first panel, and the temperature sensor can detect the temperature of the first panel through the thermal conductivity of the heat conductor.

[0018] Specifically, thermal grease can be used as the heat conductor to reduce costs while improving the durability of the temperature sensor.

[0019] Furthermore, mounting holes can be made inside the heating coating, which can be ring-shaped to improve the appearance and ensure uniform heating.

[0020] Optionally, in some technical solutions of this utility model, the circumferential wall of the temperature sensor has a gap with the wall of the mounting opening.

[0021] In this technical solution, there is a gap between the circumferential wall of the temperature sensor and the wall of the mounting opening; that is, there is a certain distance between the outer peripheral edge of the temperature sensor and the inner wall of the mounting opening, preventing the temperature sensor from contacting the heating coating after installation. Since both the temperature sensor and the heating coating require electricity to operate, the gap between the circumferential wall of the temperature sensor and the wall of the mounting opening prevents short circuits caused by contact between the energized temperature sensor and the heating coating, thus improving the safety and stability of the food warming board.

[0022] Optionally, in some technical solutions of this utility model, the panel assembly further includes an insulating layer, which is disposed between the first panel and the heating coating, or the insulating layer is disposed on the side of the first panel away from the heating coating.

[0023] In this technical solution, the insulating layer is disposed between the heating coating and the first panel, or on the side of the first 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 first panel is heated. By adding an insulating layer to the first panel, the high temperature can be prevented from affecting its insulation performance, thus improving the durability and safety of the panel assembly. Furthermore, the production cost of the first panel can be reduced, eliminating the need for additional insulation devices.

[0024] Optionally, in some technical solutions of this utility model, the panel assembly further includes electrodes, which are disposed on the first panel and electrically connected to the heating coating.

[0025] In this technical solution, the panel assembly also includes electrodes disposed on the first panel and electrically connected to the heating coating. By printing or welding electrodes at both ends of the heating coating, when using the food warmer, current can be applied to the electrodes at both ends of the heating coating. The current passing through the coating generates a current heating effect, thereby heating the coating. The heat is conducted through the first panel to heat and keep the cookware warm, which can improve heating efficiency. At the same time, using the heating coating as a heat source, the food warmer can heat cookware made of non-magnetic materials, improving the adaptability and practicality of the food warmer.

[0026] In some technical solutions of this utility model, optionally, the electrode and the coil are projected along the height direction of the warming plate, and the projection of the electrode is located outside the projection of the coil.

[0027] In this technical solution, the electrodes and coil are projected along the height of the heating plate. The projection of the electrodes is located outside the projection of the coil, which can avoid interference with the coil, thereby reducing the assembly difficulty. At the same time, it can also improve the stability of the coil and the heating coating, avoid mutual interference affecting the heating efficiency, and improve product performance.

[0028] Optionally, in some technical solutions of this utility model, the panel assembly further includes a second panel, which is arranged around the first panel; the warming plate further includes a heating film, which is disposed in the mounting cavity and arranged opposite to the second panel.

[0029] In this technical solution, the panel assembly also includes a second panel arranged around the first panel; the food warmer also includes a heating film, the heat generated by which can be transferred to the food through the second panel, thus keeping the food warm, reducing the energy consumption and working efficiency of the food warmer, and making it easier for users to use. The heating film is disposed in the mounting cavity and arranged opposite to the second panel, which improves heat transfer efficiency and also facilitates the installation of the heating film.

[0030] Optionally, in some technical solutions of this utility model, the panel assembly further includes a bracket, which is arranged around the first panel and overlaps the second panel.

[0031] In this technical solution, the panel assembly also includes a support bracket, which is arranged around the first panel and overlaps the second panel. This improves the stability of the panel assembly and facilitates the assembly of the first and second panels. The support bracket also enhances the load-bearing capacity of the panel assembly.

[0032] In some technical solutions of this utility model, optionally, the thickness of the heating coating is less than or equal to 0.1 mm.

[0033] In this technical solution, the thickness of the heating coating is less than or equal to 0.1 mm. By limiting the thickness of the heating coating, the axial height of the food warmer can be avoided. Shortening the heating coating reduces the axial height of the panel assembly, lowers the center of gravity, and improves stability.

[0034] Specifically, the thickness of the heating coating can be H2, where the thickness H2 is greater than 0 and less than or equal to 0.1 mm.

[0035] Optionally, in some technical solutions of this utility model, the distance between the heating coating and the coil is less than or equal to 10 mm in the height direction of the warming plate.

[0036] In this technical solution, the distance between the heating coating and the coil is less than or equal to 10 mm in the height direction of the warming plate. By limiting the distance between the heating coating and the coil, the axial height of the panel assembly is reduced, the center of gravity is lowered, and stability is improved.

[0037] Specifically, the distance between the heating coating and the coil can be H3, where H3 is greater than 0 and less than or equal to 10 mm.

[0038] In some technical solutions of this utility model, the heating coating may optionally include at least one of graphene coating and metal oxide coating.

[0039] 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 bonded to the first panel via printing or vapor deposition, reducing installation difficulty, eliminating the need for an additional heating device, and lowering costs. Since the graphene coating and metal oxide coating can be bonded to the first panel via printing or vapor deposition, the axial height of the first 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.

[0040] In some technical solutions of this utility model, the first panel may optionally be a microcrystalline panel; and / or the second panel may be a tempered glass panel.

[0041] In this technical solution, the first panel is a microcrystalline panel, which can improve its high-temperature resistance and enhance the durability of the panel assembly. Alternatively, the second panel can be a tempered glass panel, which can reduce the production cost of the food warmer.

[0042] Specifically, the heating temperature range set on the first panel is 40 degrees Celsius to 300 degrees Celsius.

Detailed Implementation

[0054] 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.

[0055] 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.

[0056] The following reference Figures 1 to 7 This invention describes a food warmer according to some embodiments of the present invention.

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the embodiment of the present invention, a food warming board 100 is provided, including a support assembly 110, a panel assembly 120, a coil 130, and a heating coating 140. The panel assembly 120 is disposed on the support assembly 110, and the panel assembly 120 and the support assembly 110 enclose an installation cavity 112. The panel assembly 120 includes a first panel 122. The coil 130 is disposed in the installation cavity 112 and opposite to the first panel 122. The heating coating 140 is disposed on the first panel 122 and located on the side of the first panel 122 near the coil 130.

[0058] This application provides a food warmer 100, comprising a support assembly 110, a panel assembly 120, a coil 130, and a heating coating 140. The panel assembly 120 is disposed on the support assembly 110, and the panel assembly 120 and the support assembly 110 enclose a mounting cavity 112. The panel assembly 120 includes a first panel 122, and the coil 130 is disposed within the mounting cavity 112, opposite to the first panel 122. The heating coating 140 is disposed on the first panel 122, located on the side of the first panel 122 closest to the coil 130. By applying the heating coating 140, the heating coating 140 can conduct electricity, thereby generating heat. The heat is then conducted through the first panel 122 to heat and keep the cookware warm, improving heating efficiency. Furthermore, using the heating coating 140 as a heat source, the food warmer 100 can heat cookware made of non-magnetic materials, enhancing the adaptability and practicality of the food warmer 100.

[0059] Since the coil 130 is located inside the mounting cavity 112 and opposite to the first panel 122, it can also heat the magnetic cookware placed on the first panel 122 through electromagnetic induction after being energized, thereby achieving heating and heat preservation of food. By simultaneously setting the coil 130 and the heating coating 140, it is possible to heat and preserve cookware of different materials, improving the practicality of the warming plate 100.

[0060] Specifically, by configuring the coil 130 and the heating coating 140, the warming plate 100 can achieve dual-mode heating. When heating cookware made of magnetic materials, the coil 130 and the heating coating 140 work simultaneously to improve heating and heat preservation efficiency. When heating cookware made of non-magnetic materials, the heating coating 140 generates heat, enhancing the adaptability and practicality of the warming plate 100.

[0061] Furthermore, the heating coating 140 is located on the side of the first panel 122 near the coil 130, which ensures direct heat transfer, reduces heat loss, and improves heating efficiency.

[0062] Specifically, by setting the heating device as the heating coating 140, the installation steps can be simplified, and the weight and axial height of the panel assembly 120 can be reduced, thereby achieving a thinner and lighter design for the food warming board 100, making it easier for customers to use.

[0063] This embodiment provides a food warming board 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0064] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the food warmer 100 also includes a temperature sensor 150, which is located on the side of the first panel 122 near the coil 130 and can detect the temperature of the first panel 122.

[0065] In this embodiment, the food warmer 100 also includes a temperature sensor 150, which is disposed on the side of the first panel 122 near the coil 130. The temperature sensor 150 can detect the temperature of the first panel 122, ensuring that the food warmer 100 can be maintained within the set temperature range during operation, thereby improving the practicality of the food warmer 100.

[0066] Specifically, the temperature sensor 150 can help the food warmer 100 achieve energy-saving optimization. When the temperature of the first panel 122 is detected to have reached or approached the set value, the food warmer 100 can automatically adjust the heating power to reduce unnecessary energy consumption.

[0067] This embodiment provides a food warming board 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0068] like Figure 4 and Figure 6 As shown, the heating coating 140 has a mounting port 142, through which the temperature sensor 150 passes and contacts the first panel 122.

[0069] In this embodiment, a mounting opening 142 is provided on the heating coating 140, which facilitates the insertion of the temperature sensor 150 into the heating coating 140 for easy assembly. Since the temperature sensor 150 passes through the mounting opening 142 and contacts the first panel 122, it can detect the operating temperature of the first panel 122, thereby accurately reflecting the temperature status of the heating coating 140. By monitoring and feeding back temperature information in real time, the temperature sensor 150 can help the control system achieve more precise temperature regulation, ensuring that the food warmer 100 operates stably within the set temperature range.

[0070] Furthermore, the temperature sensor 150 can directly contact the first panel 122, that is, the detection end of the temperature sensor 150 can be directly abutted against the first panel 122, which can improve the detection accuracy.

[0071] Furthermore, the temperature sensor 150 can be in indirect contact with the first panel 122, that is, a heat conductor is provided between the temperature sensor 150 and the first panel 122, and the temperature sensor 150 can detect the temperature of the first panel 122 through the thermal conductivity of the heat conductor.

[0072] Specifically, thermal grease can be selected as the heat conductor. Thermal grease has good thermal conductivity, which can improve the detection accuracy of temperature sensor 150 and avoid affecting detection due to gaps between temperature sensor 150 and first panel 122, thereby improving detection efficiency and accuracy. At the same time, indirect contact can also improve the durability of temperature sensor 150.

[0073] Furthermore, mounting holes can be made inside the heating coating 140, which can be annular in shape to improve the neatness of the appearance while ensuring uniform heating.

[0074] This embodiment provides a food warming board 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0075] The circumferential wall of the temperature sensor 150 has a gap 144 with the wall of the mounting port 142.

[0076] In this embodiment, a gap 144 is provided between the circumferential wall of the temperature sensor 150 and the wall of the mounting opening 142. This means that the outer peripheral edge of the temperature sensor 150 is a certain distance from the inner wall of the mounting opening 142, preventing the temperature sensor 150 from contacting the heating coating 140 after installation. Since both the temperature sensor 150 and the heating coating 140 require power during operation, the gap 144 between the circumferential wall of the temperature sensor 150 and the wall of the mounting opening 142 prevents a short circuit between the powered temperature sensor 150 and the heating coating 140 due to contact, thus improving the safety and stability of the food warmer 100.

[0077] Furthermore, the circumferential wall of the temperature sensor 150 and the wall of the mounting port 142 have a gap 144, that is, there is a gap between the temperature sensor 150 and the heating coating 140, thereby preventing the temperature sensor 150 and the heating coating 140 from contacting each other, avoiding short circuit between the temperature sensor 150 and the heating coating 140, and improving the stability of the warming plate 100.

[0078] Specifically, the heating coating 140 surrounds the temperature sensor 150, ensuring uniform heat distribution on the first panel 122 and preventing uneven heating of food, which could lead to overheating or underheating. The temperature sensor 150 accurately reflects the temperature of the heating coating 140. By monitoring and feeding back temperature information in real time, the temperature sensor 150 helps the control system achieve more precise temperature regulation, ensuring stable operation of the food warmer 100 within the set temperature range. A non-heating coating area is provided within the annular heating coating. By placing the temperature sensor 150 within the area enclosed by the inner periphery of the heating coating 140, the operation of the temperature sensor 150 is prevented from being affected by the heating coating 140 being powered on.

[0079] Specifically, the heating coating 140 is arranged in a ring shape. When the heating coating 140 heats up, it can ensure that the heat is evenly distributed on the first panel 122, thereby avoiding the food from being partially overheated or underheated due to uneven heating.

[0080] This embodiment provides a food warming board 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0081] The panel assembly 120 also includes an insulating layer 124, which is disposed between the first panel 122 and the heating coating 140, or the insulating layer 124 is disposed on the side of the first panel 122 away from the heating coating 140.

[0082] In this embodiment, the insulating layer 124 is disposed between the heating coating 140 and the first panel 122, or the insulating layer 124 is disposed on the side of the first panel 122 away from the heating coating 140. The insulating layer 124 improves the insulation effect of the panel assembly 120. When the food warmer 100 is in operation, the first panel 122 is heated. By adding the insulating layer 124 to the first panel 122, the high temperature can be prevented from affecting the insulation effect of the first panel 122, improving the durability and safety of the panel assembly 120. It also reduces the production cost of the first panel 122 without requiring additional insulation devices.

[0083] This embodiment provides a food warming board 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0084] The panel assembly 120 also includes an electrode 160 disposed on the first panel 122 and electrically connected to the heating coating 140.

[0085] In this embodiment, the panel assembly 120 further includes electrodes 160, which are disposed on the first panel 122 and electrically connected to the heating coating 140. By printing or welding electrodes 160 at both ends of the heating coating 140, when using the food warmer 100, current can be applied to the electrodes 160 at both ends of the heating coating 140. The current passes through the coating and generates a current heating effect, thereby achieving heating of the coating. The first panel 122 conducts heat to achieve heating and heat preservation of the cookware, which can improve heating efficiency. At the same time, with the heating coating 140 as a heat source, the food warmer 100 can heat cookware made of non-magnetic materials, improving the adaptability and practicality of the food warmer 100.

[0086] This embodiment provides a food warming board 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0087] Projecting the electrode 160 and the coil disk 130 along the height direction of the warming plate 100, the projection of the electrode 160 is located outside the projection of the coil disk 130.

[0088] In this embodiment, the electrode 160 and the coil 130 are projected along the height direction of the warming plate 100. The projection of the electrode 160 is located outside the projection of the coil 130, which can avoid interference with the coil 130, thereby reducing the assembly difficulty. At the same time, it can also improve the stability of the coil 130 and the heating coating 140, avoid mutual interference affecting the heating efficiency, and improve product performance.

[0089] Specifically, the height direction of the warming plate 100 is the direction shown in F1.

[0090] This embodiment provides a food warming board 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0091] The panel assembly 120 also includes a second panel 126, which is arranged around the first panel 122; the food warmer 100 also includes a heating film 170, which is disposed in the mounting cavity 112 and arranged opposite to the second panel 126.

[0092] In this embodiment, the panel assembly 120 further includes a second panel 126, which is arranged around the first panel 122. The food warmer 100 also includes a heating film 170, the heat generated by which can be transferred to the food through the second panel 126, thus keeping the food warm, reducing the energy consumption and working efficiency of the food warmer 100, and making it easier for users to use. The heating film 170 is disposed in the mounting cavity 112 and arranged opposite to the second panel 126, which can improve heat transfer efficiency and also facilitate the installation of the heating film 170.

[0095] In this embodiment, the panel assembly 120 further includes a bracket 128, which is arranged around the first panel 122 and overlaps the second panel 126. This improves the stability of the panel assembly 120 and facilitates the assembly of the first panel 122 and the second panel 126. The bracket 128 also enhances the load-bearing capacity of the panel assembly 120.

[0097] The thickness of the heat-treated coating 140 is less than or equal to 0.1 mm.

[0098] In this embodiment, the thickness of the heating coating 140 is less than or equal to 0.1 mm. By limiting the thickness of the heating coating 140, the axial height of the food warming board 100 can be avoided. Shortening the heating coating 140 reduces the axial height of the panel assembly 120, lowers the center of gravity, and improves stability.

[0099] like Figure 7 As shown, specifically, the thickness of the heating coating 140 can be H2, where the thickness H2 of the heating coating 140 is greater than 0 and less than or equal to 0.1 mm.

[0103] In this embodiment, the distance between the heating coating 140 and the coil 130 in the height direction of the warming plate 100 is less than or equal to 10 mm.

The heating coating 140 can be bonded to the first panel 122 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 first panel 122 via printing or vapor deposition, the axial height of the first panel 122 can be reduced, thereby reducing the axial height of the panel assembly 120. This achieves a thinner and lighter design for the food warmer 100, making it easier for customers to use and improving the stability of the food warmer 100.

[0109] This embodiment provides a food warming board 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0110] The first panel 122 is a microcrystalline panel; and / or the second panel 126 is a tempered glass panel.

[0111] In this embodiment, the first panel 122 is a microcrystalline panel, which can improve the high temperature resistance of the first panel 122 and enhance the durability of the panel assembly 120.

[0112] Specifically, the food warming board 100 is also equipped with a drive component 180 and a chassis 182. The drive component 180 can drive the chassis 182 and the panel assembly 120 to rotate, which can realize the rotation of the panel assembly 120, making it easier to display or pick up food. It can also achieve uniform heating and improve the working effect of the food warming board 100.

[0113] The food warming board 100 is also equipped with a circuit board 186, which allows for the control of the functions of the food warming board 100 and improves product performance.

[0114] Specifically, the food warmer 100 is also equipped with a power circuit board 188 to improve power supply stability. The food warmer 100 is also equipped with a cooling fan 190 to dissipate heat, improve the durability of the food warmer 100, and prevent high temperatures from affecting the use of the equipment.
