[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 5 shown, the present utility model provides a multifunctional insulation board, which includes a heating mechanism 1. The heating mechanism 1 includes a panel 11 and a bracket 14. A cover plate 2 is covered on the top surface of the panel 11. One side of the cover plate 2 is hinged to the bracket 14. A plurality of grooves 24 are arranged on the top surface of the cover plate 2, and a plurality of protrusions corresponding to the grooves 24 are arranged on the bottom surface of the cover plate 2 in contact with the panel 11. The heating mechanism 1 includes a heating element installed inside the bracket 14. When in use, the cover plate 2 is opened to expose the panel 11. The heating element is powered on to generate heat and transfer the heat to the panel 11, and then the panel 11 transfers the heat to the food placed thereon, so as to realize heating or insulation of the food. After the insulation board is used, the panel 11 will have residual heat. Further cover the cover plate 2 to cover the exposed panel 11 again, so as to prevent the user from being scalded due to direct contact with the panel 11. The grooves 24 and their corresponding protrusions can increase the heat dissipation area of the cover plate 2, increase air flow, improve the heat dissipation efficiency and reduce the heat conduction between the cover plate 2 and the panel 11, reduce the surface temperature of the cover plate 2, so that the cover plate 2 will not overheat even when the panel 11 has residual heat, thus being safer. The plurality of protrusions can also improve the strength of the cover plate 2, help to disperse the pressure of the items placed on the cover plate 2, and protect the panel 11 from damage.

[0028] Optionally, in some embodiments, both the upper and lower surfaces of the cover plate 2 are flat. The flat design reduces the places where dirt and dust accumulate, and can make the cover plate 2 easier to clean.

[0029] Furthermore, as a preferred implementation mode of the present invention rather than a limitation, the material of the cover plate 2 is heat-insulating plastic. The heat-insulating plastic has good heat-insulating performance, thus reducing the risk of the user being scalded by directly contacting the heating area 12 during the operation process. At the same time, the heat-insulating plastic material is light, which can make the cover plate 2 easy to operate.

[0030] Furthermore, as a preferred embodiment of the present invention rather than a limitation, the shape of the groove 24 is a quadrangular pyramid with the vertex facing downwards. The quadrangular pyramid-shaped groove 24 can increase the surface area of the top surface of the cover plate 2, which helps to improve the heat dissipation efficiency. Compared with a simple groove, the quadrangular pyramid design can improve the overall structural strength of the cover plate 2 and reduce deformation.

[0031] Furthermore, as a preferred embodiment of the present invention rather than a limitation, a C-shaped card slot 25 is provided on one side of the cover plate 2, and a hinge shaft 15 is provided on one side of the bracket 14. The hinge shaft 15 is snap-fitted with the C-shaped card slot 25. The snap-fitting of the hinge shaft 15 with the C-shaped card slot 25 enables the cover plate 2 to flip relative to the bracket 14. The C-shaped card slot 25 has an opening, and the hinge shaft 15 can be disengaged from the C-shaped card slot 25 through the opening of the C-shaped card slot 25, and the hinge shaft 15 can also enter the C-shaped card slot 25 through the opening of the C-shaped card slot 25, thereby realizing the separation and installation of the cover plate 2 and the bracket 14. The separation of the cover plate 2 and the bracket 14 enables the food placed on the panel 11 to be open to people around the insulation board, avoiding the situation where it is impossible to pick up the food due to the obstruction of the cover plate 2.

[0032] Furthermore, as a preferred embodiment of the present invention rather than a limitation, a chamfer is provided on the long side of the C-shaped card slot 25. Providing a chamfer on the long side of the C-shaped card slot 25 can play a guiding role, making it easier for the hinge shaft 15 to align and smoothly enter or exit the C-shaped card slot 25, thereby realizing the quick installation and disassembly of the cover plate 2 and the bracket 14. The chamfer can also reduce the friction when the hinge shaft 15 enters or exits the C-shaped card slot 25, thereby reducing the wear between the two and extending the service life.

[0033] Furthermore, as a preferred embodiment of the present invention rather than a limitation, the panel 11 is provided with a heating area 12 for heating and keeping food warm and a number of control areas 13 for controlling the operation of the heating area 12. A heating element is installed below the heating area 12, and the heat generated by the heating element is transferred to the heating area 12 of the panel 11, thereby heating the food placed on the panel. The control area 13 is provided with a number of control buttons for controlling the operation of the heating area 12, and these buttons include but are not limited to a power switch, a temperature adjustment knob or button, a timer setting, etc.

[0034] Optionally, in some embodiments, the panel 11 is only provided with a heating area 12 for heating and keeping food warm. The entire panel 11 is a heating area, which can accommodate more containers or larger containers. The entire panel being a heating area can also adapt to containers of various sizes and shapes, increasing the flexibility of use.

[0035] Further, as a preferred embodiment of the present invention rather than a limitation, the cover plate 2 is provided with at least one through hole 22 for placing tableware. Users can directly pick up and place tableware through the through hole 22, so as to heat or keep warm the food contained in the tableware. Without the need to fully open the cover plate 2 in the case of limited space. Picking up and placing tableware through the smaller through hole 22 reduces the risk of direct contact with the heating area 12 and further reduces the possibility of scalding.

[0036] Optionally, in some embodiments, the cover plate 2 is integrally formed without a hollowed-out part.

[0037] Further, as a preferred embodiment of the present invention rather than a limitation, the length of the cover plate 2 is the same as the length of the heating area 12. The cover plate 2 having the same length as the heating area 12 can ensure that the cover plate 2 completely covers the heating area 12, preventing users from accidentally touching the heating area 12 during operation, thus reducing the risk of scalding. The cover plate 2 having the same length as the heating area 12 means that the cover plate 2 does not cover the control area 13. Users can control the control area 13 without opening the cover plate 2. In combination with the through hole 22, users can control the heating area 12 to heat food with the cover plate 2 closed, improving the convenience of user operation.

[0038] Optionally, in some embodiments, the length of the cover plate 2 is the same as the length of the panel 11. The cover plate 2 having the same length as the panel 11 can ensure that the cover plate 2 completely covers the entire panel 11, including the heating area 12 and the control area 13, avoiding users from touching the heating area 12 and preventing users from accidentally touching the control area 13 to make the heating area 12 work.

[0039] Further, as a preferred embodiment of the present invention rather than a limitation, a mirror 23 is installed on one side of the bottom surface of the cover plate 2. Users can use the mirror 23 at any time when needed, whether it is to tidy up their appearance when preparing food in the kitchen or to check their appearance when using the warming plate in the office; the mirror 23 is integrated on the cover plate 2, eliminating the need for additional space to store the mirror, which is especially suitable for environments with limited space.

[0040] Further, as a preferred embodiment of the present invention rather than a limitation, a handle 21 for opening the cover plate 2 is provided on one side of the cover plate 2. The handle 21 enables users to easily open or close the cover plate 2; operating the cover plate 2 through the handle 21 can prevent users from directly contacting the heating area 12 and reduce the risk of scalding.

[0041] Further, as a preferred embodiment of the present invention rather than a limitation, the heating mechanism 1 includes a number of feet 16 for lifting the bracket 14. The feet 16 provide a certain gap between the bracket 14 and the tabletop, which helps to reduce the direct transfer of heat to the bottom surface and reduce the risk of the tabletop overheating.

[0042] Embodiment 1:

[0043] The multifunctional heat preservation board includes a heating mechanism 1. The heating mechanism 1 includes a panel 11 and a bracket 14. A cover plate 2 is covered on the top surface of the panel 11. One side of the cover plate 2 is hinged to the bracket 14. A plurality of grooves 24 are arranged on the top surface of the cover plate 2. A plurality of protrusions corresponding to the grooves 24 are arranged on the bottom surface of the cover plate 2 in contact with the panel 11. The heating mechanism 1 includes a heating element installed inside the bracket 14. During use, the cover plate 2 is opened to expose the panel 11. The heating element is energized to generate heat and transfer the heat to the panel 11. Then the panel 11 transfers the heat to the food placed thereon, thereby realizing the heating or heat preservation of the food. When the heat preservation board is not in use, the panel 11 will have residual heat. Further, the cover plate 2 is covered to re-block the exposed panel 11, thereby preventing the user from being scalded due to direct contact with the panel 11. The grooves 24 and their corresponding protrusions can increase the heat dissipation area of the cover plate 2, increase air flow, improve the heat dissipation efficiency while reducing the heat conduction between the cover plate 2 and the panel 11, and reduce the surface temperature of the cover plate 2, so that the cover plate 2 will not overheat even when the panel 11 has residual heat, thus being safer. The multiple protrusions can also improve the strength of the cover plate 2, help to disperse the pressure of the items placed on the cover plate 2, and protect the panel 11 from damage.

[0044] The shape of the groove 24 is a quadrangular pyramid with the vertex facing downwards. The quadrangular pyramid-shaped groove 24 can increase the surface area of the top surface of the cover plate 2, which helps to improve the heat dissipation efficiency. Compared with a simple groove, the quadrangular pyramid-shaped design can improve the overall structural strength of the cover plate 2 and reduce deformation.

[0045] A C-shaped card slot 25 is opened on one side of the cover plate 2. A hinge shaft 15 is arranged on one side of the bracket 14. The hinge shaft 15 is clamped with the C-shaped card slot 25. The clamping of the hinge shaft 15 with the C-shaped card slot 25 can enable the cover plate 2 to rotate relative to the bracket 14. The C-shaped card slot 25 has an opening. The hinge shaft 15 can be disengaged from the C-shaped card slot 25 from the opening of the C-shaped card slot 25, and the hinge shaft 15 can also enter the C-shaped card slot 25 from the opening of the C-shaped card slot 25, thereby realizing the separation and installation of the cover plate 2 and the bracket 14. The separation of the cover plate 2 and the bracket 14 can make the food placed on the panel 11 accessible to people around the heat preservation board, avoiding the situation where it is impossible to pick up the food due to the blockage of the cover plate 2.

[0046] A chamfer is provided on the long side of the C-shaped card slot 25. Providing a chamfer on the long side of the C-shaped card slot 25 can play a guiding role, making it easier for the hinge shaft 15 to align and smoothly enter or exit the C-shaped card slot 25, thus realizing the quick installation and disassembly of the cover plate 2 and the bracket 14. The chamfer can also reduce the friction when the hinge shaft 15 enters or exits the C-shaped card slot 25, thereby reducing the wear between the two and extending the service life.

[0047] The panel 11 is provided with a heating area 12 for heating and keeping food warm, and a number of control areas 13 for controlling the operation of the heating area 12. A heating element is installed below the heating area 12, and the heat generated by the heating element is transferred to the heating area 12 of the panel 11, thereby heating the food placed on the panel. The control area 13 is provided with a number of control buttons for controlling the operation of the heating area 12, and these buttons include but are not limited to a power switch, a temperature adjustment knob or button, a timer setting, etc.

[0048] The cover plate 2 is provided with at least one through hole 22 for placing tableware. Users can directly take and place tableware through the through hole 22, so as to heat or keep warm the food contained in the tableware. In the case of limited space, it is not necessary to fully open the cover plate 2. Taking and placing tableware through the smaller through hole 22 reduces the risk of direct contact with the heating area 12 and further reduces the possibility of scalding.

[0049] The length of the cover plate 2 is the same as the length of the heating area 12. The same length of the cover plate 2 and the heating area 12 can ensure that the cover plate 2 completely covers the heating area 12, preventing users from accidentally contacting the heating area 12 during operation, thereby reducing the risk of scalding. The same length of the cover plate 2 and the heating area 12 means that the cover plate 2 does not cover the control area 13. Users can control the control area 13 without opening the cover plate 2. Combined with the through hole 22, users can control the heating area 12 to heat food with the cover plate 2 closed, improving the convenience of user operation.

[0050] The length of the cover plate 2 is the same as the length of the panel 11. The same length of the cover plate 2 and the panel 11 can ensure that the cover plate 2 completely covers the entire panel 11, including the heating area 12 and the control area 13, while preventing users from contacting the heating area 12 and accidentally touching the control area 13 to make the heating area 12 work.

[0051] A mirror 23 is installed on one side of the bottom surface of the cover plate 2. Users can use the mirror 23 at any time when needed, whether it is to tidy up their appearance when preparing food in the kitchen or to check their appearance when using the warming plate in the office; the mirror 23 is integrated on the cover plate 2, eliminating the need for extra space to store the mirror, which is especially suitable for environments with limited space.

[0052] One side of the cover plate 2 is provided with a handle 21 for opening the cover plate 2. The handle 21 enables the user to easily open or close the cover plate 2; operating the cover plate 2 through the handle 21 can prevent the user from directly contacting the heating area 12, reducing the risk of scalding.

[0053] The heating mechanism 1 includes a number of feet 16 for lifting the bracket 14. The feet 16 create a certain gap between the bracket 14 and the tabletop, which helps to reduce the direct transfer of heat to the bottom surface and lower the risk of overheating of the tabletop.

[0054] The implementation manner of the second embodiment is as follows:

[0055] The difference between the second embodiment and the first embodiment is that both the upper and lower surfaces of the cover plate 2 are flat. The flat design reduces the areas where dirt and grime can accumulate, making the cover plate 2 easier to clean.

[0056] The panel 11 is only provided with a heating area 12 for heating and keeping food warm. The entire panel 11 is a heating area, which can accommodate more containers or larger containers. The entire panel being a heating area can also adapt to containers of various sizes and shapes, increasing the flexibility of use.

[0057] The implementation manner of the third embodiment is as follows:

[0058] The difference between the third embodiment and the first embodiment is that the length of the cover plate 2 is the same as the length of the panel 11. The same length of the cover plate 2 and the panel 11 can ensure that the cover plate 2 completely covers the entire panel 11, including the heating area 12 and the control area 13, while preventing the user from contacting the heating area 12 and accidentally touching the control area 13 to make the heating area 12 work.

[0059] Specifically, the working principle of the present invention is as follows:

[0060] During use, the panel 11 is heated by the heating element installed inside the bracket 14, and the heat is transferred from the panel 11 to the food placed thereon to achieve the effect of heating or keeping warm. The control buttons provided in the control area 13 allow the user to adjust the operating parameters of the heating area 12 to meet the heating and keeping warm requirements of different types of food.

[0061] After use, the cover plate 2 can be closed on the panel 11 to prevent the user from directly contacting the panel 11 that still has residual heat and causing scalding. The grooves 24 on the cover plate 2 match the protrusions on the bottom surface, increasing air circulation and improving the heat dissipation efficiency. At the same time, the heat conduction between the cover plate 2 and the panel 11 is reduced, ensuring that the surface temperature of the cover plate 2 is appropriate. The cover plate 2 is connected to the hinge shaft 15 on the bracket 14 through a C-shaped card slot 25, which is convenient for flipping and disassembly. At the same time, the through holes 22 provided on the cover plate 2 allow the user to take and place food without completely opening the cover plate, increasing convenience.

[0062] A mirror 23 is installed on one side of the bottom surface of the cover plate 2. The user can use the mirror 23 at any time when needed, whether it is to tidy up the appearance when preparing food in the kitchen or to check their own appearance when using the warming plate in the office; the mirror 23 is integrated on the cover plate 2, and there is no need for extra space to store the mirror, which is especially suitable for environments with limited space.

[0063] In summary, the utility model solves the problems that there will be residual heat after the traditional warming plate is used, which is easy to scald the user, and it is not convenient to store due to the residual heat.

[0064] It should be understood that the terms "first", "second", etc. are used in the utility model to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the utility model, the "first" information can also be called the "second" information, and similarly, the "second" information can also be called the "first" information. In addition, the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model.

[0065] The above is the preferred embodiment of the utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and deformations can still be made, and these improvements and deformations are also regarded as the protection scope of the utility model.
