However, since the temperature required for warming food is generally higher than the heating temperature, this type of electric heating table body cannot well take into account the needs of heating and food warming. In addition, since the structure of the electric heating table is more complicated than that of an ordinary table, it is not convenient to assemble and transport the electric heating table.

[0032] Embodiment 1
[0033] Traditional tables do not have heating and food warming functions. When the temperature is low, people will inevitably feel cold hands and feet when sitting around the table, and the hot food on the table will quickly become cold and the taste will deteriorate. There is a type of electric heating table on the market. This type of electric heating table body adds an electric heating structure to the table top to enable the table top to generate heat. When a person's hand touches the table top, the icy feeling can be eliminated, and the food placed on the table top has a heat preservation effect, in the hope of achieving the heating and food warming functions. However, since the temperature required for warming food is generally higher than the heating temperature, this type of electric heating table body cannot well take into account the needs of heating and food warming. In addition, since the structure of the electric heating table is more complicated than that of an ordinary table, it is not convenient to assemble and disassemble the electric heating table.
[0034] In order to make up for the defects of the existing electric heating table due to unreasonable structure, which makes it unable to meet the needs of heating and warming food, and is not easy to transport and assemble, the present application provides a double-layer heating table structure. Figure 1-Figure 3 , Figure 1 A structural schematic diagram of the heating table is provided. Figure 2 An exploded view of a double-layer heating table structure is provided. As can be seen from the figure, the double-layer heating table structure includes a plurality of legs 300, a table top plate 100 and a heating composite plate 200.
[0035] A plurality of upper portions of the legs 300 are provided with connectors 310 extending along the horizontal plane. The connectors 310 and the cross braces 700 are connected end to end to form a closed-loop support frame. The lower portions of the legs 300 are detachably connected to the package frame 800. The support frame and the package frame 800 are relatively spaced and are both arranged parallel to the horizontal plane. In some preferred embodiments, the cross braces 700 are square steel pipes, and the connectors 310 are square pipes adapted to the cross braces 700. Since both are square structures, after the connectors 310 are inserted into the cross braces 700, the connectors 310 cannot rotate, which helps to improve the stability of the support frame. The lower portions of the legs 300 are detachably connected to the package frame 800. When transporting the heating table, the heating composite plate 200 can be removed and then transported.
[0036] The desktop panel 100 is bonded to the top of the support frame. Specifically, the desktop panel 100 is bonded to the support frame by a silicone strip. When assembling this heating table structure, first form a closed-loop support frame by plugging the connector 310 and the cross brace 700 end to end, and then move the desktop panel 100 to the top of the support frame and bond it. The desktop panel 100 can be made of rock board so that it can heat up after being radiated with heat. The structure of the desktop panel 100 is not limited, and it can be square, circular, semicircular, etc.
[0037] The heating composite plate 200 is snapped into the package frame 800 and is configured to radiate heat to the upper and lower sides after the power is turned on; a storage layer 400 is formed between the desktop panel 100 and the heating composite plate 200, and the heating composite plate 200 is controlled by a thermostat 600. There needs to be at least one area on the upper surface of the heating composite plate 200 to form a plane, so as to place food or other objects to be heated, but it is not necessary for the upper surface of the heating composite plate 200 to be entirely flat. The thermostat 600 includes a power control circuit and a temperature adjustment button. The temperature adjustment button is exposed and installed on the surface of the heating composite plate 200 and is connected to the variable resistor in the power control circuit. The power control circuit is electrically connected to the power terminal of the heating composite plate 200. By rotating the temperature adjustment button, the current in the power control circuit is adjusted to control the output power of the heating composite plate 200, thereby adjusting the temperature of the heating composite plate 200.
[0038] The double-layer heating table adopts a modular design. The legs 300, the frame 800, the desktop board 100 and the heating composite board 200 are all customized in advance by the manufacturer. During installation, the supporting frame structure is first formed by the legs 300 and the cross brace 700, and the frame 800 is installed under the legs 300 through a detachable connector. Then the heating composite board 200 is moved into the frame 800 and connected with the frame 800, and the desktop board 100 is moved into the supporting frame and bonded with a silicone strip. The assembly process is relatively simple and convenient for transportation.
[0039] The table top 100 and the heating composite plate 200 are arranged at a relative interval to form a storage layer 400, and there is a space for taking and placing objects around the storage layer 400; the food is placed on the supporting surface of the heating composite plate 200, and the heating composite plate 200 radiates heat to the upper side after being powered on, so as to heat and sterilize the food in the storage layer 400, and the table top 100 absorbs heat and blocks the heat in the storage layer 400 from escaping upward, so as to improve the heat utilization efficiency; after the table top 100 is heated by radiation, the hand can eliminate the cold feeling of the human body by touching the table top 100, but due to the limited thermal conductivity of the material of the table top 100 and the distance between the table top 100 and the heating composite plate 200, the surface temperature of the table top 100 is lower than the temperature of the heating composite plate 200, so as to avoid the human body from feeling hot when touching the table top 100, so that the heating table has both the function of warming food and warming hands, and the heating composite plate 200 can also radiate heat to the lower side to heat and keep the human legs warm.
[0040] Please refer to Figure 1 In some embodiments, the connector 310 includes two plug-in sleeves extending from the support leg 300 in different directions. The plug-in sleeves are provided with screw holes 540 at the joints with the cross brace 700, and are screwed together by screws to increase the stability of the support frame.
[0041] In some embodiments, several components that make up the support frame and the packaging frame 800 are hollow inside to reduce the overall weight of the support frame and facilitate the transportation of the double-layer heating table structure.
[0042] In some embodiments, the heat-generating composite panel 200 includes a first radiation panel 220, a heat-generating layer 230, and a second radiation panel 240, which are sequentially bonded and stacked. A packaging coating is provided around the edge of the heat-generating layer 230 to form a packaging structure, and the power-connecting end of the heat-generating layer 230 extends out of the packaging structure. Specifically, the first radiation panel 220 and the second radiation panel 240 are of the same size and symmetrically arranged, and the heat-generating layer 230 is sandwiched between the two. The packaging coating can be a high-temperature resistant glue, and the edges of the first radiation panel 220 and the second radiation panel 240 are bonded and fixed by the high-temperature resistant glue to form an integrated structure. The first radiation panel 220 and the second radiation panel 240 can be highly dense rock plate materials, which have good acid and alkali resistance and thermal shock resistance, can prevent surface corrosion and better adapt to intermittent heating working environments.
[0043] In some preferred embodiments, the heat-generating layer 230 is attached with a heat-insulating layer 210 on the side facing away from the desktop panel 100. Specifically, the heat-insulating layer 210 is made of a material with a low thermal conductivity, such as a plastic board, an OSB board, etc. Under the heat-insulating effect of the heat-insulating layer 210, the heat transferred downward by the heat-generating layer 230 is less than the heat transferred upward, because the upper side of the heat-generating layer 230 needs to warm the food, while the lower side only needs to warm the legs of the person. Therefore, the heat-insulating layer 210 is designed so that the heat-generating layer 230 mainly radiates heat upward.
[0044] Please refer to Figure 4 In some embodiments, the heating layer 230 includes a graphene thermal conductive coating 231 and a circuit coating 232. The graphene thermal conductive coating 231 covers the opposite surfaces of the first radiation panel 220 and the second radiation panel 240 to form a surface covering, and the opposite ends of the circuit coating 232 constitute a positive electrode and a negative electrode. The opposite surfaces of the first radiation panel 220 and the second radiation panel 240 refer to the sides of the heating layer 230 that are attached to the two. Compared with the traditional line heating mode, the graphene coating that constitutes surface heating heats more evenly and has a larger heating area, and the ultra-high thermal conductivity of graphene greatly improves the electrothermal conversion efficiency.
[0045] In some embodiments, the legs 300 are strip-shaped legs 300, and a plurality of legs 300 are arranged at intervals around the periphery of the heating composite plate 200, and the heating composite plate 200 is locked by the surface of the legs 300, and a space for taking and placing objects is formed between adjacent legs 300. Through the above arrangement, the legs 300 can only partially block the side of the storage layer 400, and objects can be taken and placed around the side of the storage layer 400, making the heating table more convenient and the overall structure beautiful.
[0046] In some embodiments, the desktop panel 100 covers the top of the heat-generating composite panel 200 to increase the heating area of the desktop panel 100 , increase the heating rate of the desktop panel 100 , and improve the heat utilization efficiency.
[0047] In some possible embodiments, a shielding plate partially enclosing the storage layer 400 is provided on at least one side of the storage layer 400, and the shielding plate is configured to prevent objects on the storage layer 400 from falling. Specifically, the shielding plate can be fixed on the legs 300 or the heating composite plate 200, and surround the storage layer 400. In some preferred embodiments, the shielding plate is designed to be hinged at both ends to the legs 300 and can be flipped downward to avoid obstructing the placement of objects on the storage layer 400.
[0048] In some embodiments, the desktop panel 100 is a glass-ceramic panel, a quartz glass panel, a ceramic panel or a stone panel.
[0049] In some embodiments, the heating composite plate 200 includes an overheat protection component. Specifically, the overheat protection component includes a temperature sensor, the sensing contact of the temperature sensor is arranged close to the heating layer 230, and the thermostat 600 is electrically connected to the temperature sensor. When the detected temperature is higher than the preset temperature, the thermostat 600 controls the heating layer 230 to reduce the heating power.
[0050] Please refer to Figure 5 In some embodiments, the package frame 800 is detachably connected to the leg 300 through the connection assembly 500. Specifically, the connection assembly 500 includes a bolt 510 and a plurality of pressing plates 520. The plurality of pressing plates 520 are arranged at intervals corresponding to the plurality of legs 300 and fixed to the edges of the heat-generating composite plate 200. The pressing plates 520 are provided with a plurality of through holes 530 that match the bolts 510. The surface of the corresponding pressing plates 520 on the leg 300 forms a matching fitting plane, and the fitting plane is provided with a screw hole 540 that matches the bolt 510. The pressing plates 520 fit the leg 300 through the fitting plane, and the bolts 510 are inserted through the through holes 530 and screwed into the screw holes 540 of the corresponding leg 300, so as to fix the heat-generating composite plate 200 between the plurality of legs 300.
[0051] The specific working principle of the present application is as follows: the food is placed on the supporting surface of the heating composite plate 200, and the heating composite plate 200 radiates heat upward after being powered on, so as to heat and sterilize the food in the storage layer 400, and the desktop panel 100 absorbs heat and blocks the heat in the storage layer 400 from escaping upward, so as to improve the heat utilization efficiency; after the desktop panel 100 is heated by radiation, the hand can eliminate the cold feeling of the human body by touching the desktop panel 100, but due to the limited thermal conductivity of the material of the desktop panel 100 and the distance between the desktop panel 100 and the heating composite plate 200, the surface temperature of the desktop panel 100 is lower than the temperature of the heating composite plate 200, so as to avoid the human body feeling hot when touching the desktop panel 100, so that the heating table has both the function of warming food and warming hands, and the heating composite plate 200 can also radiate heat downward to heat and keep the human legs warm.
[0052] Embodiment 2

The heating composite plate 200200 at 60°C to 80°C can meet the demand for warming dishes, and the temperature of the table top 100 is limited to below 45°C to suit the body temperature configuration and avoid burns to the human body. The table top 100 can lock its upper temperature limit by selecting a material with a lower thermal conductivity, such as selecting a rock board as the table top 100.
